What type of food packaging should be rejected due to safety concerns?

Cans that are swollen, expanded, or dented should be rejected due to safety concerns primarily because these conditions can indicate potential spoilage or contamination. Swelling is often a sign of bacterial growth, particularly from organisms that produce gas, which can compromise the food inside and pose a serious health risk to consumers. Dented cans, especially those that are dented at the seams or heavily dented, can also potentially allow for bacteria to enter the can, leading to unsafe products.

It is critical to ensure that food packaging is intact and shows no signs of damage or compromise. Undamaged cans and intact cardboard boxes, while they may appear acceptable, do not present the same level of concern for safety as those that exhibit swelling or serious dents. In essence, the integrity of food packaging is essential in maintaining food safety, and any visible signs of compromise should lead to a raise in alarm and a decision to reject such items.
