Question

Food borne illnesses from viruses typically occur through _____

Answer 1

Foodborne illnesses from viruses are commonly transmitted through poor hygiene, such as the handling or preparation of food with unwashed hands, leading to contamination by highly infectious agents like norovirus.

Step-by-step explanation:

Food borne illnesses from viruses typically occur through poor hygiene practices. This includes when foods are handled or prepared with unwashed hands, which can lead to contamination by viruses such as the norovirus. It is important to note that norovirus is highly infectious and requires a very small infectious dose to cause illness — fewer than 20 virus particles can be enough.

Food can become contaminated when individuals who are sick with the virus — and thus shedding billions of virus particles — do not wash their hands properly after contact with stool or vomit, and then go on to handle food. Consuming the contaminated food can cause others to ingest these virus particles, leading to illness.
