Which of the following illnesses can be transmitted through food?

Hepatitis A is indeed a foodborne illness, primarily transmitted through the ingestion of contaminated food or water. This virus causes liver inflammation and can result in serious health complications. The transmission typically occurs when food handlers who are infected with the virus prepare food without proper handwashing after using the bathroom. This underlines the importance of maintaining good hygiene practices in food service settings.

In comparison, while the flu and common cold are caused by viruses that can spread from person to person, they are not typically transmitted through food. These respiratory illnesses are mainly spread through droplets when an infected person coughs or sneezes, or by touching surfaces contaminated with the viruses. Strep throat is also transmitted through respiratory droplets and contact with infected individuals, rather than through food. Understanding this distinction helps food service workers recognize the types of illnesses that can compromise food safety and public health.
