Consuming spoiled canned tomatoes can lead to foodborne illnesses such as botulism. This potentially fatal condition can cause severe muscle weakness, paralysis, and even death. Therefore, it’s essential to thoroughly examine your canned tomatoes before consumption.

Tips for Safe Consumption:

Inspect the can thoroughly for any signs of bulging, leaking, or damage.
Discard any cans that show signs of spoilage.
Avoid storing canned tomatoes at room temperature for extended periods.
Refrigerate opened canned tomatoes within 2 hours.
