which type of contaminant is most likely to cause foodborne illness?
○ foreign
○ physical
○ chemical
○ microbial

Explanation:

Foodborne illnesses are predominantly caused by microbial contaminants such as bacteria (e.g., Salmonella, E. coli), viruses (e.g., Norovirus), and parasites (e.g., Toxoplasma gondii). These microorganisms can multiply in food under favorable conditions (like improper storage temperatures) and, when ingested, can lead to illness.

• Foreign contaminants usually refer to non - food items (e.g., a piece of plastic) which are more of a physical hazard but less likely to cause widespread illness compared to microbes.
• Physical contaminants (e.g., a bone fragment) are mainly a physical risk (choking, injury) rather than a major cause of illness.
• Chemical contaminants (e.g., pesticides, heavy metals) can cause illness, but microbial contaminants are far more common in causing foodborne outbreaks due to their ability to grow and spread in food.

Answer:

Microbial
