What type of foodborne illness is caused by live pathogenic organisms?

Foodborne illness caused by live pathogenic organisms is classified as a foodborne infection. In this type of illness, microorganisms such as bacteria, viruses, or parasites enter the body through consumed food or beverages, multiply, and subsequently lead to illness. This is distinct from foodborne intoxication, wherein toxins produced by microorganisms (but not the live organisms themselves) result in illness.

A key aspect of foodborne infections is that it is the pathogen itself, not a toxin, that primarily contributes to the symptoms experienced by the individuals. Symptoms such as diarrhea, vomiting, and abdominal pain are typically associated with this type of illness as the body reacts to the presence of the live pathogens multiplying in the intestine and triggering an immune response.

Moreover, toxin-mediated illness blends characteristics from both infections and intoxications but refers specifically to situations where live microorganisms produce toxins in the gastrointestinal tract after ingestion. Chemical hazard illness involves illnesses that result from consuming chemical substances, complicating the categorization of foodborne illnesses. Therefore, foodborne infection is specifically linked to the presence of live pathogenic organisms leading to adverse health effects.
