The duration of food in a refrigerator depends on several factors, such as the type of food, the temperature of the refrigerator, the storage method, and the freshness of the food before being refrigerated.

In general, raw foods such as meat, fish, and poultry can last in the refrigerator for between 1 and 3 days. Dairy products such as milk, yogurt, and cheese can last between 5 and 7 days. Fruits and vegetables can last between 3 and 7 days, depending on the type of product.

It is important to store food properly to maximize its shelf life in the refrigerator. Raw foods should be kept in closed containers or sealed bags to avoid cross-contamination. Dairy products and cooked foods should be stored on the coldest shelves in the refrigerator. Fruits and vegetables should be kept in special drawers in the refrigerator.

In general, if a food has been in the refrigerator for more than 3-4 days, it is recommended to discard it to avoid the risk of foodborne illnesses. It is important to check and smell the food before consuming it to ensure that it is still fresh and safe to eat.
