Canned food is convenient, economical, and shelf-stable, making it a popular choice for many consumers. But what happens when canned food is exposed to extreme heat? Is it safe to eat canned food that has been in the heat?
Generally speaking, if canned food has been exposed to temperatures above 90°F (32°C) for more than a few hours, it should not be consumed. Extreme heat can cause the can to swell and potentially rupture, leading to spoilage of the contents inside. Additionally, bacteria may begin to grow in the can due to the high temperature.
It is important to remember that canned food should always be stored in a cool and dry place. If it is stored in direct sunlight or near other sources of heat, such as a stove or oven, this could cause the can to become too hot. Additionally, leaving canned food in a hot car for an extended period of time should also be avoided.
If you are unsure whether your canned goods have been exposed to extreme heat:
- Look for physical signs such as swelling or bulging of the can.
- Smell the contents of the can. If there is an off-odor or foul smell coming from it, discard it immediately.
- Check the expiration date on the can.
If it has expired, do not eat it.
In summary:
It is generally not safe to eat canned goods that have been exposed to extreme heat for more than a few hours. If you are unsure whether your cans have been exposed to excessive temperatures, check for physical signs of spoilage and discard any cans with an off-odor or expired date.
Conclusion:
It is not recommended that you eat canned food that has been in the heat for longer than a few hours as this could lead to spoilage of its contents and potential bacterial growth. Always store your cans in cool and dry places away from direct sunlight or other sources of heat.
