Importance of Sanitizing Dishes in a Commercial Kitchen

Sanitizing dishes is a crucial step in maintaining a clean and healthy environment in a commercial kitchen. It helps to eliminate harmful bacteria and viruses that can cause foodborne illness, which is a major concern for any foodservice establishment. In fact, the Centers for Disease Control and Prevention (CDC) estimates that every year, one in six Americans gets sick from consuming contaminated food.

To ensure proper sanitation, dishes must be thoroughly cleaned, rinsed, and sanitized. Cleaning removes visible dirt and food particles, while rinsing removes any remaining soap or detergent. Sanitizing, on the other hand, kills any remaining microorganisms that may be present on the dishes.

There are several methods for sanitizing dishes, including using a commercial dishwasher or a three-compartment sink. In a dishwasher, dishes are exposed to high temperatures and chemicals such as chlorine bleach or quaternary ammonium that kill bacteria and viruses. In a three-compartment sink, dishes are washed in hot, soapy water, rinsed in clean water, and then sanitized in a solution of either chlorine or quaternary ammonium.

It is important to note that the concentration of sanitizing solution and the water temperature used for washing and rinsing must be carefully monitored to ensure proper sanitation. The FDA Food Code requires a minimum water temperature of 110°F for washing and 180°F for sanitizing. Test strips can be used to check the concentration of sanitizing solution and ensure that it is at the appropriate level.

In addition to dishes, it is also important to sanitize all food contact surfaces, such as countertops, cutting boards, and cooking equipment, to prevent the spread of harmful bacteria. Chairs, tables, and hard surfaces should also be cleaned and sanitized regularly.

Proper cleaning and sanitation practices not only prevent the spread of harmful bacteria and viruses but also help to maintain the cleanliness and overall appearance of a commercial kitchen. Regular cleaning and sanitizing can also extend the life of equipment and prevent rust and other damage.

In conclusion, proper sanitation is essential for any foodservice establishment to ensure the safety and well-being of its customers. By following proper cleaning and sanitizing procedures, foodservice establishments can prevent the spread of harmful bacteria and viruses and maintain a clean and healthy environment for all.
