What condition must a spatula meet before being placed back in the mayo bin?

A spatula must meet the condition of being clean on both sides before being placed back in the mayo bin to ensure food safety and hygiene. This requirement is crucial because any residue or contamination from previous use could introduce harmful bacteria or spoil the quality of the mayonnaise. By ensuring that the spatula is clean on both sides, the staff can maintain proper food handling practices and uphold the standards necessary to prevent cross-contamination and ensure customer safety. This practice aligns with health regulations and promotes a clean working environment.
