Question

which one of the following food contaminations would be suspected if the end of a can of tomatoes had begun to swell? clostridium botulinum norovirus salmonella typhi shigella spp

Explanation:

Clostridium Botulinum is an anaerobic bacterium that can grow in improperly canned foods (like canned tomatoes). It produces gas as it grows, causing the can to swell. Norovirus is spread via contaminated food but doesn't cause can swelling. Salmonella Typhi and Shigella spp. are typically associated with contaminated water or food but don't produce gas in canned goods to cause swelling.

Answer:

A. Clostridium Botulinum
