Final answer:
Norovirus and Hepatitis A are two viruses linked to ready-to-eat food and shellfish from contaminated waters, causing stomach and liver inflammation respectively.
Step-by-step explanation:
Two viruses commonly associated with ready-to-eat food and shellfish sourced from contaminated waters are Norovirus and Hepatitis A. Norovirus is known for causing inflammation of the stomach and intestines, often resulting in gastroenteritis, and is infamous for outbreaks on cruise ships. On the other hand, Hepatitis A affects the liver and can lead to symptoms like jaundice, fatigue, and abdominal pain. Both of these viruses can contaminate a variety of foods, including leafy greens, fresh fruits, and shellfish like oysters. It is crucial for food handlers to practice good hygiene and for all foods to be properly prepared, cooked, and stored to prevent the spread of these viruses.
