Question

Late blowing (bulging of cans) defect in canned foods is caused by:

• A. Clostridium foetidum
• B. Coliform
• C. Bacillus cereus
• D. Bacillus subtilis

Hint:

Ensure sterilization protocols during canning to eliminate spore-forming bacteria.

Answer 1

The Correct Option is A

Late blowing in canned foods is caused by Clostridium foetidum, an anaerobic spore-forming bacterium. This microorganism produces gas during its metabolic activity, leading to bulging of the cans. Such defects not only spoil the food but can also pose serious health risks if consumed. Proper sterilization and hygiene during canning are essential to prevent this issue.
