Which of the following is NOT a method to ensure food safety?

Using expired ingredients is indeed not a method to ensure food safety. In fact, utilizing ingredients that are past their expiration date can pose serious health risks, as they may harbor harmful bacteria, mold, or other pathogens that can lead to foodborne illnesses. Expired ingredients may not maintain their quality or safety, potentially endangering consumers.

On the other hand, proper cooking, frequent hand washing, and regular equipment sanitization are all essential methods of ensuring food safety. Proper cooking helps to eliminate harmful microorganisms in food, while frequent hand washing prevents the transmission of pathogens from hands to food. Regular equipment sanitization ensures that surfaces and utensils are kept free from contaminants, further safeguarding food from potential hazards. These practices collectively contribute to a safer food preparation environment.
