How to tell if canned foods are bad

Answer

Look for bulging or leaking cans, damaged or dented cans, food that has changed color, smell, or texture, or food with mold. If you see any of these signs, throw the food away.

Bulging or leaking cans

A bulging or leaking can is a sign that they can have been compromised and that bacteria may have gotten inside. This is because the can is not airtight, which allows bacteria to grow and produce gas. If you see a bulging or leaking can, it is important to throw it away immediately.

Damaged or dented cans

Even if a can is not bulging or leaking, damage to the can could still allow bacteria to get inside. This is because the damage can create small holes in the can, which bacteria can use to enter. If you see a damaged or dented can, it is best to throw it away to be safe.

Food that has changed color, smell, or texture

If the food in a can has changed color, smell, or texture, it is best to throw it away. This is because these changes are often signs that bacteria have grown on the food. Bacteria can cause food to spoil and make it unsafe to eat.

Food that has mold or other visible signs of spoilage

Mold is a type of fungus that can grow on food. Mold is a sign that bacteria have grown on the food and that the food is spoiled. If you see mold on food, it is important to throw it away immediately.

If you see any of these signs, it is important to throw away the canned food. Do not try to save it by cooking it or by opening the can and draining the liquid. Eating bad canned food can make you sick.
