Which of the following is NOT a reason that requires a variance for food processing?

Temperature regulation does not typically require a variance for food processing because it is a standard practice to ensure food safety. Food safety regulations provide established temperature controls that must be adhered to in order to inhibit the growth of harmful bacteria and to ensure proper food preservation. These temperature requirements are based on extensive research into food safety and do not generally necessitate an exception or variance, as they are essential to maintain food quality and ensure consumer safety.

In contrast, the use of nitrites in smoked meats, preservatives in food, and the inclusion of sugar in canning can pose unique safety concerns that might require an operator to seek a variance. These practices may significantly alter the way food is processed and stored, potentially impacting the safety and integrity of the final product. Therefore, a variance is often necessary to operate outside of the established regulations while ensuring that alternative methods meet safety standards.
