Lead Opinion
OPINION
Appellants, Scott’s Marina at Lake Grapevine, Ltd. d/b/a Silverlake Marina (Scott’s Marina), Just for Fun of North Texas, Inc. (JFF), and Silver Lake Marina Store, Inc. (the Store), appeal a judgment entered in favor of appellee, Allen Johnathan Brown, that awarded Brown $676,800 for past and future actual damages, $10,667.80 for court costs, and post-judgment interest at a rate of five percent per annum. We affirm.
Because the issues presented by appellants primarily challenge the sufficiency of the evidence, we will limit the background to a general overview of the factual background and procedural history of the case. We will discuss the evidence more fully in the analysis of each of appellants’ issues below.
Brown was employed to work weekends at the Store during the summer of 2005. The Store was owned by Scott’s Marina, but had been leased to JFF. Brown was hired by JFF and was paid by JFF.
On June 11, 2005, Brown was working the cash register at the Store when he heard a “whoosh-type” noise and was immediately struck by a “godawful smell.” A substance began to backup and overflow out of the hub drain
The following weekend, the hub drain again backflowed on multiple occasions. On these instances, two other Store employees assisted Brown in clean up of the spillages. Plumbers were called to the Store on June 20, and apparently installed backflow valves to the hub drain line. Regardless, no further backflows occurred after June 19.
During the second weekend, Brown developed a cough and a sore throat. He indicated that the glands in his neck started to swell. Nonetheless, Brown attempted to work through his developing illness. However, due to severe vomiting and diarrhea, Brown eventually had to seek medical attention on July 5. Brown’s illness worsened from July 5 to July 11, when Brown had his mother take him to the emergency room because he was vomiting uncontrollably. Brown was hospitalized and diagnosed with enteroviral meningitis and Lemierre’s Syndrome. To prevent the spread of these conditions, doctors tied off one of Brown’s jugular veins. Brown spent twelve days in the hospital due to this illness. After his release from the hospital, Brown continued to have medical and emotional problems that restricted his everyday life.
Brown filed suit against the appellants contending that the spillage that he was required to clean up in the Store on the weekends of June 11th and 18th of 2005 was sewage containing human feces, and that this exposure to human feces caused Brown’s acute and continuing illnesses. At the trial, Brown offered the expert testimony of Itzhak Brook on the issue of causation. Brook, a leading expert in the field of anaerobic infectious disease, opined that, in reasonable medical probability, Brown’s exposure to sewage containing human feces at the Store was the proximate cause of his enteroviral meningitis and Lemierre’s Syndrome. At the close of evidence, the case was submitted to the jury who returned a verdict in favor of Brown. Specifically, the jury found that appellants were negligent; that Scott’s Marina was 60 percent responsible, JFF was 20 percent responsible, and the Store was 20 percent responsible; and awarded Brown damages of $250,000 for past physical pain and mental anguish, $75,000 for future
Scott’s Marina filed a brief on its own behalf and JFF and the Store filed a joint brief on their behalf. The issues presented by Scott’s Marina are (1) the trial court abused its discretion in admitting Brook’s unreliable testimony, (2) the evidence was insufficient to establish that Brown was exposed to sewage at the Store, and (3) the jury’s award of actual damages cannot be sustained. The issues presented by JFF and the Store are (1) the trial court erred in admitting Brook’s testimony over appellants’ objection, (2) the evidence is insufficient to support the jury’s implied finding that Brown was exposed to human waste, and (3) the evidence is insufficient to support the jury’s implied finding that appellants should have foreseen the risk that Brown could be exposed to human waste. We will address appellants’ issues in a slightly different order starting with the issue of whether the evidence was sufficient to establish that Brown was exposed to human waste.
Sufficiency of the Evidence — Exposure to Human Feces
By both of their second issues, appellants contend that the evidence was insufficient to support the jury’s implied finding that Brown was exposed to sewage containing human feces by cleaning up the backfiowed spillage in the Store on the weekends of June 11 and 18 of 2005. The significance of this implied finding is that Brook’s expert causation testimony assumes that Brown was exposed to human feces containing enterovirus, and that this exposure led to Brown’s subsequent medical problems. Additionally, JFF and the Store contend, by their third issue, that the evidence was insufficient to support the foreseeability of human feces backflow-ing into the Store.
Standard of Review
When a party challenges the legal sufficiency of the evidence supporting a jury finding, we consider the evidence in the light most favorable to the finding and indulge every reasonable inference that supports it. See City of Keller v. Wilson,
When a party challenges the factual sufficiency of the evidence, we consider all of the evidence and will set aside the finding only if the evidence supporting the finding is so weak or so against the overwhelming weight of the evidence that the finding is clearly wrong and unjust. Cain v. Bain,
Analysis
Appellants contend that the overwhelming weight of the evidence proves that the configuration of the plumbing was such that it would not have been possible for wastewater or sewage containing human waste to have backfiowed into the Store on the occasions in issue. Due to
Appellants contend that the evidence conclusively established that the drain line from the Store was not directly connected to a sewage line that was used to evacuate the sewage from boats. Brown contends that there was significant conflict in the evidence that would allow the jury to reasonably conclude that appellants altered the configuration of the drainage system between the time of the spillages in question and subsequent inspections of that drainage system. In fact, at the conclusion of the hearing on appellants’ motion for judgment notwithstanding the verdict, the trial court stated, “The findings of the jury can only be understood if you believe the defendants changed the configuration of the pipes after the incidents, and then came to court and lied about it. There is testimony to support this. There’s no evidence to refute it.” Further, it is undisputed that the hub drain line was connected to the gray water burger dock line and that backflow prevention devices were not installed on these lines. While we conclude that there is some evidence that would “refute” the theory that appellants altered the configuration of the drainage system and then lied about it, we agree with the trial court that there is some evidence to support this conclusion. As such, we must defer to the jury’s reasonable resolution of this conflict in the evidence. See City of Keller,
However, concluding that the pump-out sewage line was connected to the hub drain line is not sufficient to establish that the spillage was sewage containing human feces. Appellants contend that the configuration of the pump-out sewage system was such that, at the time of the spillage, it would have been impossible for sewage from the pump-out sewage line to have backflowed into the Store. According to appellants, this is because the two pump-outs operated in conjunction with one another based on vacuum suction at the time of the spillage and the multiple openings in the hub drain line and gray water burger dock line would have prevented the pump-outs from being able to push the sewage up through the hub drain line. Brown’s ultimate theory is that appellants installed a second motor on the pump-out sewage line in the Spring of 2005 that allowed the pump-out lines to operate independently of one another, and that this motor provided the force sufficient to push the sewage through the hub drain line.
The evidence relating to whether the pump-outs operated independently or in conjunction at the time of the backflow is in sharp conflict. Evidence that supports the determination that the pump-outs were working independently and on their own motors in June of 2005 was presented through the testimony of Rulene Reynolds, manager of Silver Lake Marina at the time of the incidents, J.B. Strohkirch, maintenance man for the marina, and Tom Sanford, superintendent for the marina. However, each of these witnesses also provided testimony that, at the time of the incidents, the pump-out lines were working in conjunction with one another, with only one motor, based on vacuum suction.
Further bolstering the jury’s determination that the pump-outs pushed sewage into the Store is the testimony providing that the pump-outs could only operate using vacuum suction if they were not connected to the hub drain line. In other words, the evidence established that it would not be possible for the pump-outs to be connected to the hub drain line and still operate in conjunction, using only a single motor, because the openings at the end of the hub drain line would have prevented the creation of a vacuum. However, if the pump-outs operated independently, with each having their own motor, the pump-outs would have been able to operate even if connected to the hub drain line. In fact, according to Mark Jensen, appellants’ engineering expert, the motor would allow the waste from the pump-outs to be pushed through the hub drain line causing the backflow of waste containing human feces into the Store.
In addition, a review of the entire record reveals that there was significant disagreement among the eyewitnesses about the characteristics of the substance that back-flowed into the Store. Some of the witnesses testified that the substance was clear and smelled like rotten food and grease. Other eyewitnesses testified that the substance was dirty and that it smelled like sewage. Obviously, this testimony creates a conflict in the evidence regarding the characteristics of the substance that backflowed into the Store. The jury clearly resolved this conflict by determining that the substance that backflowed into the Store was sewage containing human feces. Because there is evidence to support the jury’s implied finding that the substance that backflowed into the Store contained human feces, we must conclude that there was legally and factually sufficient evidence to support this implied finding. See Walker & Assocs. Surveying, Inc. v. Austin,
As the evidence is sufficient for the jury to have concluded that the substance that backflowed into the Store was sewage containing human feces, regardless of JFF and the Store’s knowledge of the configuration of the plumbing, it was foreseeable that making an employee clean up sewage containing human feces by use of a mop and bucket could expose the employee to viruses contained within the human feces. The combined effect of the evidence that allows for a reasonable inference that JFF and the Store were aware of the plumbing’s configuration together with JFF and the Store requiring Brown to clean up a backflowed spillage that the jury could reasonably find to have been sewage containing human feces is enough to establish that Brown’s exposure to human feces was foreseeable.
Consequently, we overrule appellants’ second issues and conclude that the evidence was sufficient to support the jury’s implied finding that the substance that backflowed into the Store was sewage containing human feces. Likewise, due to the evidence allowing the jury to reasonably conclude that JFF and the Store were aware of the plumbing’s configuration and that Brown was required to clean up human feces by JFF and the Store, the evidence is sufficient to support the jury’s implied finding that Brown’s injury was
Admissibility of Expert Causation Testimony
By their first issues, appellants contend that the trial court erred in admitting the expert medical testimony on causation of Dr. Brook over appellants’ objections that the testimony was unreliable. While their issue is presented in terms of admissibility, a review of the arguments of appellants reveal that appellants are actually contending that the evidence is insufficient to establish the reliability of Brook’s expert testimony on causation. As such, our analysis of the sufficiency of the evidence supporting the reliability of Brook’s testimony will determine our assessment of the admissibility of Brook’s testimony. See Merrell Dow Pharms., Inc. v. Havner,
For expert testimony to be admissible, the expert must be qualified, the testimony must be relevant to the issues in the case, and the testimony must be based on a reliable foundation. TXI Transp. Co. v. Hughes,
In determining whether expert testimony is reliable, a reviewing court must employ “an almost de novo-like review and, like the trial court, look beyond the expert’s bare testimony to determine the reliability of the theory underlying it.” Gross,
The Texas Supreme Court has articulated six nonexclusive factors appellate courts should consider in determining whether scientific testimony is reliable:
*155 (1) The extent to which the theory has been or can be tested;
(2) The extent to which the technique relies upon subjective interpretation of the expert;
(3) Whether the theory has been subjected to peer review and publication;
(4) The technique’s potential rate of error;
(5) Whether the underlying theory or technique has been generally accepted as valid by the relevant scientific community; and
(6) The non-judicial uses that have been made of the theory or technique.
Hamer,
Analysis
a. The Extent to Which the Theory Has Been or Can Be Tested
Appellants’ challenge of the testing of Brook’s theory basically challenges the theory in two particular aspects: (1) Brook assumed that Brown was exposed to wastewater or sewage containing human feces, and (2) Brook failed to establish an accepted causal link between exposure to human feces and development of Lem-ierre’s Syndrome.
As for Brook’s assumption that Brown was exposed to human feces, his testimony is clear that his opinion is premised on this assumption. Thus, the weight that the jury could reasonably afford Brook’s opinion was dependent on the jury’s resolution of the factual issue regarding whether Brown was exposed to human feces when he cleaned up the backflowed spillage at the Store. As addressed above, there was sufficient evidence presented to allow the jury to reasonably conclude that the back-flowed spillage contained human feces. However, because Brook acknowledged this assumption and because the validity of this assumption relied on the jury’s determination of fact, the validity of Brook’s assumption goes to the weight to be ascribed to the evidence rather than to its admissibility. See LMC Complete Auto., Inc. v. Burke,
As for the causal connection between exposure to human feces and Lemierre’s Syndrome, we believe that there was sufficient evidence presented during the pretrial hearing to establish that a causal chain between exposure to human feces and Lemierre’s Syndrome is accepted. Dr. Louis Marshall Sloan, appellants’ expert witness, testified in his deposition that the primary cause of enteroviral infection is exposure to fecal matter. Sloan also acknowledged the textbook, Principles and Practice of Infectious Diseases, to be commonly relied upon as authoritative by infectious disease specialists. Portions of this textbook offered by Brown in his pre-trial evidence identifies that waste-water and sewage are common sources of enteroviral infections. While Sloan and Brook disagreed regarding whether the enterovirus or fusobacterium caused Brown’s pharyngitis that led to the Lem-ierre’s Syndrome, Brown offered a peer reviewed article as well as citation to the authoritative textbook that Lemierre’s Syndrome is an uncommon, but known, result of a viral pharyngitis. After review
b. The Extent to Which the Theory Has Been Subjected to Peer Review and Publication
Appellants next challenge the lack of peer review or publication of Brook’s theory. Essentially, appellants complain that Brook did not prove that Brown was exposed to human feces that contained en-terovirus, and that he did not cite any published support for a scientifically significant link between enteroviral and/or fu-seobacteria exposure and the types of illnesses which Brown suffered.
As addressed above, Brook premised his testimony on the clearly stated assumption that Brown was exposed to sewage containing human feces when Brown cleaned up the backflowed spillage in the Store. Both Brook and Sloan as well as much of the published medical articles that were submitted by Brown acknowledge that en-terovirus can be found in human feces, and that the most common form of transmission of enteroviral infections is oral-fecal transmission.
As to the claimed lack of published support for a link between enteroviral infection and Brown’s medical issues, the published articles appear to support Brook’s explanation of the link between the enter-oviral infection causing the pharyngitis, which then created the conditions necessary for Brown to develop Lemierre’s Syndrome. Sloan opined that Brown’s Lemierre’s Syndrome was caused by fuso-bacterium alone. However, fusobacterium is a natural bacteria that is in the mouths of all humans. This fusobacterium is prevented from causing infections by the body’s natural immune system. According to Brook and the medical articles offered by Brown, when a virus weakens a person’s immune system, it can create conditions where the fusobactrium can be released and can cause pharyngitis. Thus, while the experts disagree regarding whether the enterovirus or the fusobacter-ium caused Brown to develop the pharyngitis that became Lemierre’s Syndrome, there is published support for a scientifically significant link between Brown’s exposure to human feces and his development of Lemierre’s Syndrome.
c. The Extent to Which Other Likely Causes Were Ruled Out
Appellants next contend that Brook’s expert testimony on causation was unreliable because he failed to rule out other likely causes of Brown’s illness. This is an important factor in assessing the reliability of an expert’s opinion testimony. See Transcon. Ins. Co.,
Both experts in this case opined that the most common source of enteroviral infection is the oral introduction of human fecal matter. Brook testified that the sewage that backflowed into the Store was, within a reasonable degree of medical probability, the source of Brown’s enteroviral infection. Sloan testified that, if the backflowed spillage was sewage and if the incubation period matched, then it was a “higher possibility” as the source of Brown’s enteroviral infection. Further, many other likely causes of enteroviral infection were considered and ruled out both by Brook as well as by the physicians that treated Brown at Baylor Regional Medical Center at Grapevine. Finally, Brown provided an affidavit that attested that he was not exposed to
In the final analysis, Brook was able to rule out the most likely other causes of Brown’s contracting the enterovi-ral infection.
d. Incubation Period and Brown’s Illness
Another challenge to Brook’s reliability raised by appellants is that the period between Brown’s exposure to the spillage and his development of symptoms does not correlate to the medically accepted incubation period for enterovirus. Sloan emphasized this alleged inconsistency in Brook’s testimony.
Sloan indicated that the normal incubation period for an enteroviral infection is three to five days with the extremes being two to twelve days.
As there is evidence that supports Brown’s onset of symptoms occurring on June 20, well within the incubation periods identified by both experts, we do not conclude that the delay in Brown exhibiting symptoms is evidence that Brook’s expert opinion is unreliable.
Conclusion
As our review of the record reveals that the evidence was sufficient to support the reliability of Brook’s expert testimony opining that Brown’s exposure to human feces at the Store caused his enteroviral infection
Sufficiency of the Evidence — Damages
By Scott’s Marina’s third issue, appellants challenge the sufficiency of the evidence to support the jury’s award of actual damages to Brown.
As a general principle, we need to remain mindful that the amount of damages awarded is uniquely within the jury’s discretion. Missouri Pac. R.R. Co. v. Roberson,
The standard of review for a challenge contending that an award of actual damages was excessive is the same as is used in a factual sufficiency challenge. See Maritime Overseas Corp.,
Appellants specifically challenge the following damages findings: (1) $89,000 for loss of past wages, (2) $102,300 for loss of earning capacity in the future, (3) $60,000 for medical expenses incurred before trial, (4) $100,000 for future medical expenses, (5) $250,000 for past physical pain and mental anguish, and (6) $75,000 for future physical pain and mental anguish.
Lost Earning Capacity
Appellants’ first challenge to the jury’s award of damages goes to the sufficiency of the evidence to support the awards for Brown’s lost earning capacity. Lost wages refers to the actual loss of income due to an inability to perform a specific job from the time of injury to the time of trial. Koko Motel, Inc. v. Mayo,
Looking to the evidence in support of the jury’s award of $89,000 for Brown’s lost earning capacity between injury and trial, the jury was presented evidence that Brown was a hard working young man that held two jobs before the injury. The jury also heard that Brown was a fairly skilled automobile mechanic, and that he was attempting to become more skilled in this area through working at an auto repair and performance garage, where he earned approximately $10 per hour, and through pursuing an education in marketing and management in the automotive aftermarket industry. As a side business, Brown ran an automobile repair service out of his house, charging other students $20 per hour to perform various repairs to their vehicles. Further, the jury heard evidence that Brown was unable to maintain employment because of the frequency with which he continued to have illnesses and setbacks due to his exposure to human feces at the Store.
Thus, we conclude that the evidence was sufficient to establish that, prior to the injury, Brown had the capacity to work, at least, a 40-hour work week, and the evidence of the skills Brown possessed in automobile repair is sufficient to establish a reasonable inference that he would have had the capacity to work in the auto repair industry, and that he would have earned at least $10 per hour. See Burry,
Turning to appellants’ challenge of the sufficiency of the evidence to support the jury’s award of $102,300 for future lost earning capacity, the jury heard evidence that Brown was unable to hold steady employment due to the frequency with which he became ill and needed medical attention. After repeated attempts, Brown has been unable to progress toward a college degree due to the physical and psychological effects of his exposure to human feces at the Store. The jury also heard evidence that, because of seizures Brown began to experience after the in-
Thus, we conclude that the evidence was sufficient to allow the jury to conclude that Brown’s future earning capacity was diminished by the illnesses he developed as a result of his exposure to human feces in the Store. The jury was able to infer that Brown would have a substantial life expectancy based on his health and vitality prior to the present incident, as well as the fact that he was only 23 years old at the time of trial. See Borden, Inc. v. Guerra,
Medical Expenses
Turning to appellants’ challenge to the sufficiency of the evidence to support the jury’s award of $60,000 for Brown’s past medical expenses, we note that appellants’ entire argument is premised on their contention that the evidence is insufficient to establish a causal connection between Brown’s exposure to human feces in the Store and his resulting illness. However, as thoroughly addressed in the issues above, we have concluded that the evidence was sufficient to allow the jury to conclude that Brown was exposed to human feces and that this exposure was the producing cause of Brown’s past medical expenses. As such, we affirm the jury’s award of $60,000 for medical expenses incurred by Brown in the past.
Appellants also challenge the sufficiency of the evidence supporting the jury’s award of $100,000 for medical expenses reasonably expected to be incurred by Brown in the future. For future medical expenses to be recoverable, the evidence must show that there is a reasonable probability that such expenses will be incurred in the future. Columbia Med. Ctr. of Las Colinas v. Bush,
In the present case, we conclude that the evidence is sufficient to establish a reasonable probability that Brown will
Physical Pain and Mental Anguish
Finally, appellants challenge the sufficiency of the evidence to support the jury’s award of damages to Brown for physical pain and mental anguish.
In addressing both the jury’s award of $250,000 for past physical pain and mental anguish and $75,000 for future physical pain and mental anguish, appellants’ arguments are confined solely to the sufficiency of the evidence to support the jury’s award for mental anguish damages. None of the appellants challenged the trial court’s charge to the jury which asked for a lump sum for both physical pain and mental anguish damages. Appellants did not draw the trial court’s attention to their complaint that there was insufficient evidence to support an award of mental anguish damages, separate and apart from physical pain damages, during the charge conference, in closing arguments, or in a motion for new trial. See Ake v. Monroe, No. 04-05-00751-CV,
Conclusion
Having overruled each of appellants’ issues, we affirm the judgment of the trial court.
CAMPBELL, J., dissenting.
Notes
. The hub drain of a soda fountain machine is the receptacle at the bottom of the machine that is designed to catch spillage from the machine.
. Both Strohkirch and Sanford testified that a second motor was installed in March of 2005 in their pre-trial depositions. However, at trial, each changed their testimony to indicate that the second motor was installed in the Fall of 2005.
. We acknowledge that Brown contends that appellants waived their issue regarding the reliability of Brook's expert testimony. However, when the video of Brook’s deposition testimony was offered at trial, the appellants timely objected to this evidence “based on the hearing that we've had outside the presence of the jury with regard to Daubert and those matters.” The trial court overruled the objection and the videotaped deposition was shown to the jury. As such, appellants' objection to the admission of Brook’s testimony at trial simply re-urged their objections made pretrial, and were sufficient to preserve error. See Tex.R.App. P. 33.1.
Further, appellants can challenge the sufficiency of the evidence supporting the reliability of Brook's testimony so long as they objected to the reliability of the evidence before trial or when it is offered at trial. See Maritime Overseas Corp. v. Ellis,
. We disagree with the dissent's characterization of Brook’s testimony that he was able to rule out other possible sources of Brown’s contraction of enterovirus as conclusory. A number of other possible sources of Brown’s exposure to enterovirus were ruled out by information Brown provided to the doctors that treated his enteroviral infection, and this information was documented in Brown’s medical records which were reviewed by Brook. Further, Brown's affidavit provided additional evidence ruling out his exposure to other sources of enterovirus.
. Brook’s identification of the incubation period for enteroviral infection was that the typical case would become symptomatic between twelve hours to three days with the outer extreme being symptoms appearing fourteen days after exposure.
.The dissent focuses on the legal sufficiency of the evidence supporting whether the sewage containing human feces that backflowed into the Store contained enterovirus, and whether Brown’s cleaning of this sewage was how Brown contracted the enteroviral infection. While we agree with the dissent's analysis that there were ways in which Brown’s evidence that the sewage contained enterovi-rus could have been stronger, we disagree with the dissent’s conclusion that the evidence establishing the likely presence of en-terovirus in the sewage containing human feces was legally insufficient.
The evidence that supports the conclusion that the sewage that backflowed into the Store contained enterovirus and that it was the source of Brown’s contraction of the en-teroviral infection includes: Brook's testimo
Likewise, as discussed in footnote 4, we conclude that there is substantial evidence ruling out other sources of enterovirus, and disagree with the dissent's characterization that other sources were ruled out solely on the basis of Brook’s bare conclusion.
. While the issue of the sufficiency of the evidence to support the damages awarded is raised only by Scott’s Marina, under the authority of Texas Rule of Appellate Procedure 9.7, JFF and the Store joined in and adopted by reference all issues and arguments advanced by Scott’s Marina. See Tex.R.App. P. 9.7. Thus, we will consider the issue of the sufficiency of the evidence to support the damages awarded as being asserted by all appellants.
. This calculation is based on a $10 per hour job working 40 hours per week.
. We note that appellants do not challenge the sufficiency of the evidence to support the $60,000 amount of past medical expenses. As such, we may not review that issue. See Allright, Inc. v. Pearson,
. Even were we to conclude that the evidence is insufficient to support any award of damages to Brown for past or future mental anguish, it is possible that the jury’s entire awards of past and future physical pain and mental anguish damages were to compensate Brown for the physical pain he has and will suffer.
Dissenting Opinion
Justice, dissenting.
The Court’s opinion discusses the admissibility of the opinion testimony of It-
The sufficiency of appellee Allen Johnathan Brown’s evidence of causation depends on the testimony of Dr. Brook. At trial, Dr. Brook testified that enteroviruses are common viral forms.
Dr. Brook predicated his testimony and opinions on the assumption that Brown was exposed to “wastewater” and “sewage” through the “spillage” in the marina store. He believed the spillage was sewage because, “[t]he water looked dirty, they (sic) smelled bad, they smelled like sewage.” But he knew not whether an analysis was performed to determine the content of the material to which Brown was exposed.
Thus Brown contracted an enterovirus, Dr. Brook opined, either from exposure to human fecal material bearing the virus or water from the hand-washing of individuals who had contacted the virus. Concerning the means of exposure, Dr. Brook concluded, “there’s a lot of possibilities.”
Establishing proximate cause requires a sufficient showing of cause in fact and foreseeability. D. Houston, Inc. v. Love,
In cases of exposure to a toxic substance, there is often no direct evidence of causation. Merrell Dow Pharmaceuticals, Inc. v. Havner,
Plaintiffs may, nevertheless, rely on epidemiological studies demonstrating an increased risk of their particular injury resulting from exposure to the substance in question to create a fact issue on causation. Havner,
But we are not told of epidemiological studies demonstrating the risk of contracting enterovirus from exposure to wastewa-ter containing human sewage. Does all human feces contain an enterovirus? If, as Dr. Brook testified, enterovirus is found in the bodily excretions of people who are “sick,” what percentage of the Tarrant County population is “sick” in that way at any one time? Both testifying experts, Drs. Brook and Sloan, agreed oral-fecal contact is the “most common” and the “primary” means through which an entero-virus enters the body, but such a statement does not tell anything about the likelihood that any particular sample of feces or wastewater contains an enterovirus.
This case is similar to Schaefer v. Texas Employers’ Insurance Association,
Despite the fact enteroviruses will survive
In the health care liability context, the Texas Supreme Court recently said in Jelinek v. Casas,
The court’s discussion in Jelinek is equally applicable here. Nothing in this record explains why Dr. Brook’s opinion Brown contracted an enterovirus from his “exposure to sewage water” is superior based on science. Rather, his opinions rested on his ipse dixit.
I would reverse the judgment of the trial court and render judgment that Brown take nothing. Because the Court does not, I respectfully dissent.
. He agreed with the statement enteroviruses are one of the most common forms of viruses "second to the common cold.”
. According to a brochure included in Brown’s medical records, "[e]nteroviruses are small viruses. The enteroviruses that occur in the United States include coxsackieviruses and echoviruses. Polioviruses are also included in the term "enterovirus,” but they have been eradicated from the United States by vaccination. In all, more than 60 different types of enteroviruses have been identified.” A medical dictionary defines enterovirus as "[a] genus of picornaviruses, including polio-viruses, coxsackieviruses, and echoviruses, that infect the gastrointestinal tract and often spread to other areas of the body, especially the nervous system.” The American Heritage, Stedman’s Medical Dictionary 269 (2002).
. Evidence showed neither the liquid nor any of its contents was tested. Later, on cross-examination, Dr. Brook agreed that testing a sample of the spillage would have allowed •him to offer more accurate opinions. He added, however, "there are a lot of other circumstantial information that allows me to deduce it without having the sample.”
.Dr. Brook referred to enterovirus as "a virus we know that lives or is present in sewage, in places where water that is dirty and contaminated,” and further testified:
A. It is called the name, "entero," because it usually is found in the gastrointestinal tract, and is often found in the stool and other excretions of people who are sick.
Q. Okay.
A. It can also be found in the hands of people who don't wash their hands. Now, theoretically and practically, the workers— and that's why they warn people who work in restaurants, to wash your hands.
Q. All right.
A. If somebody's infected with enterovirus, and they go to the bathroom, don’t wash*163 their hands, and go back and prepare food, this is how people can get infected.
Q. Okay.
A. Or if they wash their hands, that water that they wash their hands in, may go to the sewage and contaminate the sewage, as well.
Q. Okay.
A. So there's a lot of possibilities.
. Although the parties do not discuss it, similarly missing from this record is any evidence of the group or serotype of the enterovirus Brown’s culture grew.
. Such viruses will survive in such an environment but will not multiply, according to Dr. Brook.
. Responding to a question about the possibility of exposure to an enterovirus from changing a diaper, Dr. Brook said:
Theoretically, any place that has stool on it, or human excrement, can infect somebody, if they don’t wash their hands. But, in [Brown’s] case, we know what was the cause, that it is more likely than not that that [sic] caused it, and that was exposure to sewage water.
.Others also mopped the substance that backflowed into the marina store but without demonstrating signs of sickness. Dr. Brook accounted for this inconsistency with the conclusion that these individuals were "sub-clinical,” which he later defined to mean, "somebody's ill, but they don’t manifest any symptoms.”
. “The term ‘ipse dixit ’ means 'something asserted but not proved’ and is literally translated ‘he himself said it.’ " Marvelli v. Alston,
