What is a sniff test?

A sniff test is a simple and quick method used to determine the freshness or spoilage of a food item by smelling it. This test is commonly used for checking the quality of perishable items such as milk, meat, fish, and vegetables.

When performing a sniff test, one should smell the food item to see if it has a normal, fresh odor or if there is any strong or unpleasant smell present. A foul or sour smell indicates that the food has likely gone bad and should not be consumed.

While a sniff test can be a helpful tool in determining the freshness of a food item, it is not always foolproof. Some foods may still be unsafe to eat even if they do not have a noticeable odor. It is always best to use the sniff test in conjunction with other methods of food safety, such as checking for signs of spoilage, proper storage, and following expiration dates.
