How often should kitchen utensils and equipment be sanitized?

Kitchen utensils and equipment should be sanitized after each use. This is the standard food safety practice because utensils come into contact with raw and cooked foods, each of which may carry bacteria, allergens, or other contaminants.

Sanitizing after each use prevents cross-contamination, which occurs when bacteria from one food item (especially raw meat, poultry, or fish) are transferred to another food via a shared utensil, cutting board, or surface. Pathogens such as Salmonella, E. coli, and Campylobacter can survive on surfaces for hours or even days if not properly cleaned.

The sanitizing process involves first washing the utensil with hot soapy water to remove visible food residue, then rinsing, and finally applying a sanitizing solution (such as a dilute bleach solution or commercial sanitizer) or using very hot water. The utensil should then be air-dried.

Sanitizing only daily, weekly, or monthly leaves utensils contaminated between cleaning sessions, creating opportunities for bacterial growth and foodborne illness. In a busy kitchen where utensils may be used multiple times a day with different foods, after-each-use sanitization is essential.
