Jacob De La Fuente pled guilty to two counts of mailing threats to injure in violation of 18 U.S.C. § 876(c). Pursuant to the Mandatory Victims Restitution Act of 1996 (MVRA), 18 U.S.C. § 3663A, the district court ordered De La Fuente to pay $39,492.56 in total restitution to the United States Postal Service (USPS), the Los An-geles County Fire Department’s Hazardous Materials Division (LA HazMat) and the Los Angeles County Health Department (LAHD). De La Fuente challenges the district court’s restitution order on appeal. He argues that the MVRA does not apply because his was not a “crime of violence.” He also argues that USPS, LA HazMat and LAHD do not qualify as victims entitled to restitution under the MVRA. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.
I.
On October 15 and 16, 2001, De La Fuente mailed two letters that contained a white powder and that included notes with the following text: “Surprise Anthrax Yor[sic] it Die Bitch.” De La Fuente sent his first letter to Diane Olin, a former boss. He sent his second letter to Laura Caudillo, a former girlfriend.
A USPS employee at a mail processing and distribution center in California found the letter addressed to Laura Caudillo when it broke open during processing. Acting in response to the white powder that spilled out of De La Fuente’s letter, USPS evacuated 229 employees from its processing and distribution center, lost 1,374 employee work hours, and incurred cleanup costs, for a total monetary loss of $37,550. Three LA HazMat officials also spent six hours responding to the incident, for a total LA HazMat loss of $1,609.92. LAHD tested De La Fuente’s letters for anthrax; its testing services were valued at $332.64. LAHD’s tests established that the white powder in De La Fuente’s letters was not anthrax.
On March 29, 2002, the government filed an indictment charging De La Fuente with two counts of mailing threats to injure in violation of 18 U.S.C. § 876. After De La Fuente pled guilty to both counts, the *769 district court sentenced him to thirty-seven months’ imprisonment and three years’ supervised release. The district court also ordered De La Fuente to pay $37,550 in restitution to USPS, $1,609.92 to LA Haz-Mat and $332.64 to LAHD.
II.
Congress passed the MVRA in 1996 as a supplement to the Victim and Witness Protection Act of 1982 (VWPA), 18 U.S.C. § 3663.
See United States v. Grice,
The MVRA applies, inter alia, to “crime[s] of violence,” as defined in 18 U.S.C. § 16, if an “identifiable victim or victims has suffered a physical injury or pecuniary loss.” 18 U.S.C. § 3663A(c)(l). On appeal, De La Fuente argues that his was not a crime of violence subject to the MVRA.
A.
Because De La Fuente challenges the district court’s crime-of-violence determination for the first time on appeal,
1
we review that determination only for plain error. Fed.R.Crim.P. 52(b);
see also United States v. Zink,
B.
A crime qualifies as a “crime of violence” if it is
(a) an offense that has as an element the use, attempted use, or threatened use of physical force against the person or property of another, or
(b) any other offense that is a felony and that, by its nature, involves a substantial risk that physical force against the person or property of another may be used in the course of committing the offense.
*770
18 U.S.C. § 16. In this case, only § 16(a) is potentially applicable. The crime of sending a threat to injure is complete when the perpetrator places his threatening letter in the mail, and there is little risk of physical force being used in the course of writing or mailing a threatening letter.
See United States v. Nilsen,
In deciding whether the district court committed plain error in determining that the crime of mailing a threat to injure is a crime of violence under § 16(a), we apply the categorical approach set out in
Taylor v. United States,
When applying
Taylor’s
categorical approach, we first “look to the statutory definition of the crime, rather than to the defendant’s specific conduct.”
United States v. Sandoval-Venegas,
C.
The two elements of the crime of mailing a threat to injure are that (1) the defendant’s letter contained a threat to injure and (2) that the defendant knowingly caused the threatening letter to be deposited in the mail. 18 U.S.C. § 876(c);
2
see also United States v. Sirhan,
De La Fuente argues that his own offense conduct undermines our analysis because a threat of anthrax poisoning is not a threat of forceful conduct, as the term “force” ordinarily would be understood. We are not persuaded. Anthrax is a physical substance that causes injury to the human body, and De La Fuente’s letters clearly threatened death by way of physical contact with anthrax spores. The injury and pain caused by anthrax infection may not always be immediately obvious to the person exposed, but the bacteria’s physical effect on the body is no less violently forceful than the effect of a kick or blow.

III.
In criminal cases, restitution may compensate victims only “for actual losses caused by the defendant’s criminal conduct.”
United States v. Gamma Tech Indus., Inc.,
A.
We review de novo the district court’s application of the MVRA and its conclusion that USPS, LA HazMat and LAHD are victims of De La Fuente’s crime.
United States v. Hackett,
B.
De La Fuente first argues that any costs incurred by USPS, LA HazMat and LAHD were not direct and proximate results of his crime.
1.
“[T]he main inquiry for causation in restitution cases [is] whether there was an intervening cause and, if so, whether this intervening cause was directly related to the offense conduct.”
United States v. Meksian,
We recently applied these principles in
Hackett,
where we held that a defendant who pled guilty to aiding and abetting methamphetamine manufacture could be ordered to pay restitution to an insurance company for property damage caused when a co-defendant started a fire by placing a jar of chemicals used to manufacture methamphetamine on a hot plate.
We reached the opposite conclusion in
Meksian,
where we reversed a restitution order because of an inadequate causal link.
2.
The record in this case establishes that the losses incurred by USPS, LA HazMat and LAHD were all directly related to De La Fuente’s offense conduct. Depositing the Olin and Caudillo letters in the mail was a necessary element of De La Fuente’s crime, 18 U.S.C. § 876(c), and that act led directly to the possible anthrax exposure in a USPS mail processing center.
See United States v. Quillen,
C.
We are not persuaded by De La Fuente’s additional argument that USPS, LA HazMat and LAHD were not “harmed” within the meaning of the MVRA because they only “incurred costs.” The MVRA applies when a victim or victims has suffered either a physical injury or a “pecuniary loss,” 18 U.S.C. § 3663A(c)(l)(B), and the statute specifically provides for restitution in cases that involve economic harm but not bodily injury,
id.
§ 3663A(b)(l).

As we recently not
*774
ed in Hackett, the MVRA “directs that both physical injury and financial loss are compensable.”
IV.
For the foregoing reasons, the district court’s restitution order is AFFIRMED.
Notes
. De La Fuente did not raise the issue of restitution in the sentencing memorandum he submitted to the district court. At his sentencing hearing De La Fuente did argue that the MVRA should not be applied to him, but only "based on the fact that the intended victims in this case were not postal workers.” De La Fuente never challenged the government’s crime-of-violence analysis and, when the district court noted in issuing its ruling that there was "no dispute” regarding the crime-of-violence determination, De La Fuente did not object.
. This statutory section also makes it a crime to send kidnapping threats. We take no position as to whether mailing a threat to kidnap also qualifies as a crime of violence.
. We note that this conclusion ensures consistency with the decisions of our sister circuits. The Fourth and Eighth Circuits have concluded that mailing threatening communications is a crime of violence.
United States v. Weddle,
. We have recognized that creation of a latent risk of injuiy does not meet the requirements of § 16(a) where the defendant directs no physical force against the person injured.
See United States v. Hernandez-Castellanos,
. In
United States v. Follet,
. This section of the MVRA provides that when a defendant’s crime results in property damage, loss or destruction, the defendant should be ordered to
(A) return the property to the owner of the property or someone designated by the owner; or
(B) if return of the property under subpara-graph (A) is impossible, impracticable, or inadequate, pay an amount equal to—
(i) the greater of—
*774 (I) the value of the property on the date of the damage, loss, or destruction; or
(II) the value of the property on the date of sentencing, less
(ii) the value (as of the date the property is returned) of any part of the property that is returned[.]
18 U.S.C. § 3663A(b)(l). Although these calculation instructions are not easy to apply where property is rendered temporarily unusable, rather than completely destroyed or permanently damaged, we agree with the Third Circuit that in this specific factual situation the districts court's "only practical option was to order [De La Fuente] to pay the cost of ensuring that the mail room was in the same condition as just prior to the time it became unusable.”
