Which pathogen type typically does not grow in food and is often transferred via water?

The correct answer highlights that parasites are not typically associated with food growth. Unlike bacteria, which thrive and multiply in food under the right conditions, parasites generally require a host organism to survive and complete their life cycle. Many parasites are transmitted through contaminated water. For instance, waterborne parasites, such as Giardia and Cryptosporidium, can cause illness when ingested but do not replicate within food items themselves.

Bacteria and fungi, on the other hand, are known to grow and multiply in food, while viruses can also spread through food but do not grow in it — they require a host to reproduce. Understanding the specific characteristics of different types of pathogens is crucial for effective food safety practices and prevention of foodborne illnesses.
