When washing dishes or foodservice equipment, cleaning and sanitizing need to happen together – each on its own isn’t enough to protect your guests from pathogens. But even when sanitizer is used after cleaning, Statefoodsafety.com says it can fail to do its job or even spread germs if not used at the proper temperature and concentration for the appropriate amount of time. Chlorine, iodine and quaternary ammonium compound sanitizing solution all have different temperature requirements. If a sanitizer is mixed with water that’s not the right temperature, it may be less effective. Use test strips to check you are using the appropriate concentration of each sanitizer as it might be dangerous at the wrong proportions. Finally, let each sanitizer work for the required amount of time to make sure it’s effective.
Chemicals abound in and around your kitchen. Just don’t let them create a food safety problem. To avoid cross-contamination, Statefoodsafety.com advises you store chemicals away from food storage and contact areas, label all chemicals clearly and wash hands after handling them. In case of spillage, discard the excess chemical — don’t put it back into its original container. Be aware of any pesticides used on produce you buy and wash those ingredients or use other approved methods for removing pesticide residues. Also note that chemicals that may be in your cooking equipment and utensils: Avoid using copper, lead and pewter cookware and utensils, which can leach harmful chemicals into foods.
When using and storing chemicals for sanitizing and cleaning at your restaurant, make sure you take steps to minimize the chance for spills and contamination. Any chemicals you use should be in clearly labeled containers that are stored on low shelves away from food. Make sure your employees know when to avoid combining certain chemicals — chlorine and ammonia, for example, generate toxic fumes when mixed. Better yet, consider using automated dispensers for the chemicals you use. They can help ensure you’re using the appropriate amounts in the recommended concentrations and can also minimize your cleanup.
