Q

FDA Food Code
identifies the types of foods as ready-to-eat:

A

• Raw animal foods that cooked
(i.e., rotisserie chicken), frozen (i.e., sushi)
• Raw fruits and vegetables that are washed
• Fruits and vegetables that cooked for hot-holding
• All potentially hazardous foods that cooked and then cooled
• Bakery items, such as bread, cakes, pies, fillings, or icing, for which further cooking is not required
for food safety
• Substances derived from plants, such as spices, seasonings, and sugar
• Plant foods for which further washing, cooking, or other processing is not required for safety and from which rinds, peels, husks, or shells, if naturally present, are removed
• Dry, fermented sausages (i.e., dry salami or pepperoni), salt-cured meat, and poultry products
(i.e., prosciutto ham, country cured ham, and Parma ham), and dried meat and poultry products
(i.e., jerky or beef sticks) produced in accordance with USDA guidelines and treated to destroy
pathogens
• Thermally processed low-acid foods (i.e., smoked fish or meat packaged in hermetically sealed
containers
