Foodborne Illness第 29 / 240 题
Which statement correctly distinguishes viruses from bacteria in food safety?
a.Viruses cannot multiply in food; they need a living host, so they are typically transmitted by infected workers and contaminated water
b.Viruses grow rapidly in the danger zone like bacteria
c.Viruses are destroyed easily by refrigeration
d.Bacteria require a living host to reproduce
解析
Viruses such as Norovirus and Hepatitis A cannot reproduce in food; they need a living host, so they spread mainly through infected food workers, contaminated water, and the fecal-oral route. Bacteria, by contrast, can multiply rapidly in TCS food within the danger zone. This is why worker hygiene and exclusion are the key controls for viral contamination.
