Step-by-step explanation:
The most common transmission form for hepatitis A in foodborne illness outbreaks involving ready to eat foods is contaminated food. Hepatitis A virus (HAV) is typically transmitted via the fecal-oral route, which can occur when an infected food handler prepares food without proper hygiene. This can include a variety of items such as leafy greens, fresh fruits, and shellfish like oysters. Ensuring proper sanitation and following food safety practices are essential in preventing the spread of this virus.
