Which of the following is NOT a high violation?

Improper thawing practices are indeed classified as a high violation because they can lead to the growth of harmful bacteria in food. Proper thawing methods are critical to maintaining food safety, as thawing at improper temperatures can promote bacterial growth, increasing the risk of foodborne illnesses.

In contrast, the other options represent violations that present immediate or significant health risks. For example, falsified temperature logs can conceal dangerous food storage temperatures that might lead to spoiled or unsafe food. Employee health issues, such as illness or symptoms that could transmit disease, pose serious health threats to customers. Flies touching food surfaces can also introduce harmful pathogens, making this a critical violation as well.

By recognizing the severity of these various health and safety violations, it becomes clear that while improper thawing practices are important, they do not represent the highest level of risk compared to the other situations listed.
