Which of the following is NOT typically a cause of can bulging?

The correct choice indicates that aging food products are not typically a cause of can bulging. Canned foods can last for extended periods; however, the physical integrity of the can is more directly affected by factors such as temperature abuse, pressure changes, and incorrect sealing.

When food products are improperly sealed or subjected to temperature fluctuations, gases produced by microbiological activity or chemical reactions can build up inside the can. This pressure increase can lead to bulging. Aging food products, while they may deteriorate in quality, are unlikely to produce the same immediate physical signs like bulging unless they are also compromised by one of the other factors mentioned.

Recognizing the conditions that can lead to can bulging is crucial for food safety, as it helps in identifying whether the contents may be unsafe to consume. Understanding these principles ensures proper handling and storage of canned goods to prolong their shelf life and maintain safety standards.
