American Home Assurance Co. v. Greater Omaha Packing Co., Inc
819 F.3d 417
8th Cir.2016Background
- 2007 E. coli O157:H7 outbreak traced by PFGE/MLVA to frozen hamburger patties produced by Cargill; Cargill recalled 845,000 pounds and settled personal-injury claims totaling about $25.3 million and $548,604 in business costs.
- Cargill sued Greater Omaha (one of four suppliers whose trim went into the August 16 production) for breach of a June 2, 2006 supplier guarantee and related warranty claims, alleging Greater Omaha shipped trim contaminated with E. coli O157:H7.
- Epidemiological traceback for three non-Cargill cases (Hawaii, Missouri, New York) linked consumed beef to Greater Omaha production dates; two Ohio cases predated Greater Omaha’s implicated production and lacked MLVA subtyping.
- Cargill’s experts (epidemiologists) testified that molecular subtyping plus traceback and epidemiological data support Greater Omaha as the source; Greater Omaha challenged expert methodology and moved to exclude related evidence.
- District court admitted the experts and a December 2007 FSIS Notice of Intended Enforcement (NOIE); jury returned a general verdict for Cargill for $9 million; district court granted summary judgment to Cargill on Greater Omaha’s tortious-interference counterclaim.
Issues
| Issue | Plaintiff's Argument (Cargill) | Defendant's Argument (Greater Omaha) | Held |
|---|---|---|---|
| Admissibility of expert testimony | Experts used PFGE/MLVA plus epidemiological traceback; methodology reliable and fit the facts | Experts cherry-picked favorable cases and ignored Ohio cases, so methodology unreliable under Rule 702/Daubert | Court affirmed admission; methodology sufficiently reliable and admissible; Ohio cases go to weight and impeachment, not exclusion |
| Admission of FSIS NOIE & related documents | NOIE probative of unsanitary conditions at time of relevant production and of spike in positive samples | Documents prejudicial, confusing, and not sufficiently probative | Admission affirmed: relevant to sanitation and sampling issues; probative value not substantially outweighed by prejudice |
| Jury instructions re: contract formation and implied-warranty disclaimer | Contract could comprise multiple documents; jury may decide contract scope; no implied-warranty-disclaimer instruction required because Cargill lacked record evidence of assent to invoice disclaimers | Jury should have been instructed that invoices after shipment disclaim warranties and limit damages | Instructions affirmed: allowing jury to decide contract composition was proper; no entitlement to warranty-disclaimer instruction given lack of evidence Cargill received/invoked invoices |
| Summary judgment on tortious-interference counterclaim | (N/A for plaintiff) | Greater Omaha relied on NYT article and reporter emails attributing statements to Cargill’s investigator to support interference claim | Affirmed grant of summary judgment to Cargill: Greater Omaha failed to produce admissible evidence (articles/emails were hearsay) and did not show how they could be proved admissibly at summary judgment stage |
