Why Would a Commercially Canned Chili Can Explode and Spray Food?

Ever had a surprising and messy experience with a recently purchased can of commercially canned chili exploding inside your cabinet? The good news is, there are several potential reasons for such a situation. Understanding these can help prevent future occurrences and ensure food safety.

Temperature Changes

The primary culprit in many cases is temperature fluctuations. If the can was stored in a hot and sunny spot, such as near a stove or in direct sunlight, and then moved to a cooler environment, the internal pressure could build up rapidly. This can lead to an explosive release of contents, often spraying the interior of your cabinet with chili and other food particles.

Over-Pressurization

Another issue could be improper canning or a defect in the can itself. If the canning process was not correctly performed, or there was a flaw in the can, the pressure inside might build up due to fermentation or improper sealing. Uncontrolled fermentation can release gases that increase the pressure inside the can, leading to an explosion.

Damaged Can

Physical damage to the can itself, such as dents, rust, or other kinds of compromise in the can's structure, can also play a role. Damage can affect the seal, allowing bacteria to enter and produce gas. This pressure buildup can eventually cause the can to burst.

Microbial Contamination

Even more concerning is the possibility of microbial contamination, especially with anaerobic bacteria. These bacteria can survive the high-pressure canning process and produce carbon dioxide as a byproduct. The presence of such bacteria suggests that the canning process was incomplete or unsanitary, allowing these microorganisms to thrive and potentially cause an explosion.

Handling an Exploded Can

If you encounter an exploded can, it's crucial to handle the situation carefully. Avoid consuming the food and dispose of it properly to prevent contamination. In some cases, the bacteria causing the explosion could be harmful, leading to food poisoning.

Preventive Measures and Action

To ensure food safety and prevent such incidents, it's important to:

Store cans in a cool, dry place away from heat sources. Check cans for dents, rust, or other signs of damage before use. Follow proper canning and storage procedures.

Recognizing and addressing the root causes of can explosions is crucial. If you suspect contamination or irregularities, notify the vendor, manufacturer, and your local health department immediately. This proactive approach can help prevent others from facing similar issues and ensure public health and safety.
