If hygiene audit in a food enterprise happens only before festivals, what is the weakness?

Correct answer: Lack of routine monitoring

The direct answer is A: lack of routine monitoring. Hygiene means keeping food, hands, equipment, surfaces, storage, and work habits safe every day, not only before a festival. If an audit happens just once, unsafe practices between audits may remain unnoticed for a long time. Regular checks can detect dirty equipment, poor handwashing, incorrect temperatures, pest signs, cross-contamination, and unsafe storage early. Option A correctly identifies the weakness: monitoring is occasional instead of continuous. Option B, sales will always increase, is not a weakness and is not guaranteed; hygiene checking does not automatically guarantee sales. Option C, customer complaints will end, is also an unsupported result; complaints may continue if problems are not corrected. Option D, food shelf life will become infinite, is scientifically impossible because all food has limits and storage conditions matter. Therefore, the enterprise needs a daily or scheduled hygiene system with records, corrective action, and follow-up. Exam cue: safe food requires continuous control, not seasonal cleaning.
