Food poisoning claim glossary
Foodborne-illness investigations use medical, laboratory, epidemiologic, and supply-chain terms. These definitions explain how the pieces fit together and why a recall or a shared meal is important but not automatically conclusive.

- Case definition
- The criteria public-health investigators use to decide which illnesses count as part of an outbreak investigation, such as symptoms, dates, exposure, and laboratory findings.
- Causation
- The connection between the defendant's conduct or product and the injury. A case can fail even when conduct was careless if the available evidence does not connect that conduct to the harm claimed.
- Cross-contact
- The unintended transfer of an allergen from one food, utensil, surface, or preparation area to another food.
- Damages
- The losses a claim seeks to recover. Depending on the facts and governing law, these can include medical costs, lost income, future care, pain, disability, disfigurement, or loss of support.
- Defendant
- The person or organization against whom a civil claim is made. One incident can involve several possible defendants with different duties and insurance policies.
- Incubation period
- The time between consuming a contaminant and developing symptoms. It varies by pathogen and helps investigators assess possible exposures.
- Liability
- Legal responsibility for an injury. Liability depends on the applicable law and provable facts, not simply on whether someone was hurt.
- Outbreak
- Two or more similar illnesses associated with a common exposure, as determined through public-health investigation.
- Recall
- A firm's removal or correction of a product that regulators consider violative or potentially harmful. A recall is relevant evidence but does not establish individual causation by itself. Read the related guide.
- Statute of limitations
- A law that limits the time for filing a claim. The deadline varies by state, claim type, defendant, and sometimes the date the injury was or could reasonably have been discovered.
- Traceback
- The process of following a food through distribution records toward its source to identify where contamination may have occurred.
- Whole genome sequencing
- A laboratory method used by public-health agencies to compare the genetic fingerprints of pathogens from people, food, and environmental samples.
Terms are not conclusions
A definition explains a concept; it does not establish that the concept applies to a particular event. State law, contracts, medical records, product identity, insurance language, and other facts can change the analysis.
