Canned food can be a great way to have a long-term food storage option, but many people are concerned about how heat affects the shelf life of canned food. After all, cans are made of metal and they can easily become very hot in warm temperatures. So, does canned food go bad in the heat?
The short answer is yes, canned food can go bad in the heat. Cans are made of metal and when left in warm temperatures for extended periods of time, the contents inside the cans can spoil and become dangerous to eat. This is because high temperatures can cause bacteria to grow rapidly, leading to spoilage.
In addition to potential spoilage from bacteria growth, cans that become too hot may also bulge due to increased pressure inside the cans. This is caused by a chemical reaction that takes place when liquids inside the cans reach a certain temperature. If this happens, it is best to discard the contents as they may be dangerous to consume.
To avoid having canned food spoiled by heat, it is important to store them in cool places such as pantries or cupboards away from direct sunlight or other sources of heat. It is also important to check on canned food regularly and discard any cans that appear bulged or show signs of leakage.
In conclusion, it is true that canned food can go bad in the heat due to bacterial growth and increased pressure inside the cans. To avoid having canned food spoiled by heat, it is important to store them in cool places away from direct sunlight or other sources of heat and check on them regularly.
