What is a can of food called when one or both ends bulge outward due to bacterial action or gas?

A can of food that has bulging ends due to bacterial action or gas buildup is referred to as a "Springer." This condition indicates that there is a change in pressure within the can, often caused by the growth of bacteria that generate gas as a byproduct of their metabolism. The bulging can signify that the contents may be spoiled or unsafe to consume, as it may indicate the presence of harmful pathogens.

While the other terms may suggest various issues with canned food, they do not accurately describe the condition of a can that is bulging due to internal pressure. Recognizing a "Springer" is crucial for food safety, as consuming food from such a can can lead to foodborne illness. Acknowledging the dangers associated with altered canned products is vital for maintaining health and safety standards in culinary practices.
