Certified Professional Food Safety (CP-FS) Practice Exam

A foodborne illness is classified as intoxication when what condition is met?

1. A toxin is produced by bacteria in the food prior to ingestion

2. The food is consumed without cooking

3. Presence of parasites in the food

4. Food was contaminated post-cooking

The correct answer is: A toxin is produced by bacteria in the food prior to ingestion

A foodborne illness is classified as intoxication when a toxin is produced by bacteria in the food prior to ingestion. In this scenario, the bacteria produce harmful substances (toxins) that can cause illness, regardless of whether the bacteria themselves are still present in the food when it is consumed. This is distinct from other forms of foodborne illnesses where the organism causes disease primarily through infection, meaning the microbes enter the body and then grow, leading to illness. In the context of food safety, understanding the mechanism behind intoxication is crucial because it highlights the importance of proper food handling and preparation to prevent toxin production. For example, improper food storage or cooking can lead to conditions that allow bacteria to produce toxins, which can then lead to serious health issues upon consumption.
