Sanitation Certification Practice Test

Which of the following is a valid reason to reject canned goods?

1. They are labeled correctly

2. They have no rust or dents

3. They are swollen or dented

4. They have clear expiration dates

The correct answer is: They are swollen or dented

Swollen or dented canned goods are significant red flags indicating potential contamination or spoilage. When a can swells, it often suggests that bacteria, such as botulinum, may be present inside, producing gas that causes the can to bulge. This can compromise the integrity of the food and safety for consumption. Although minor dents may not always indicate a problem, significant dents, especially if found on the seam of the can, can lead to bacterial contamination. In contrast, cans that are labeled correctly, lack rust or dents, and have clear expiration dates signify that they are well-maintained and safe for consumption, making them unsuitable reasons for rejection. The condition and physical state of the can play a pivotal role in food safety, and swollen or dented conditions are clear indicators that the contents could be hazardous.
