Within food businesses, the personal hygiene of food handlers is one of the most fundamental practices to prevent food contamination and ensure compliance with food safety regulations. This starts with effective handwashing.
The efficiency of handwashing, however, is not solely dependent on the act itself but also on the temperature of the water used. While we may take it for granted, the decision to use warm water over cold or hot water can significantly impact the ability to provide safe to eat foods and prevent contamination of food.
In this article, we will delve into the reasons why it is important for Food Handlers to use warm water when washing their hands to ensure food safety and compliance.
Before we explore the specifics of water temperature it is essential to understand the core principles of handwashing. Proper hand hygiene is the cornerstone of food safety protocols and aims to eliminate harmful microorganisms from the hands of food handlers. In food establishments, employees handle a variety of ingredients, utensils, and surfaces, making handwashing a critical practice to mitigate the risk of contamination.
The Food Safety Standards code therefore requires that Food Handlers must wash their hands whenever they are likely to be a source of contamination. This includes between handling food, bathroom breaks, touching any part of your body, after using the toilet, after handling waste, and after handling raw foods or allergens.
Water temperature plays a pivotal role in the effectiveness of handwashing. While it may seem like a minor detail, the choice between hot, cold, or warm water can have a substantial impact on the transfer of harmful microorganisms in a facility. Let’s explore some key reasons why warm water is the preferred choice for handwashing in food-related settings.
One of the most significant advantages of using warm water for handwashing is the fact that it is a comfortable temperature. Comfortable water temperatures encourage individuals to wash their hands for an adequate amount of time. This is crucial because the duration of handwashing is directly related to the removal of contaminants.
The Food Standards code requires that five steps must be taken during handwashing. Food handlers must wet hands under warm running water, lather hands with soap, wash hands, wrists and between the fingers then rinse in clean water and dry thoroughly with a paper towel.
When water is too cold or too hot, individuals are more likely to rush through the handwashing process, potentially missing critical steps and not dedicating enough time to thorough cleansing. Warm water, on the other hand, is more comfortable to use, promoting a longer and more effective handwashing process.
Excessively hot or cold water can be harsh on the skin. Cold water can cause the skin to become dry and chapped leading to cracks and discomfort. On the other hand, hot water can strip the skin of its natural oils, also resulting in dryness and irritation.
When skin is damaged or chapped, it creates small openings that can harbor and protect harmful microorganisms. This poses a significant food safety risk as microorganisms can hide and multiply in these crevices, making it more challenging to remove them through handwashing. Warm water strikes a balance between comfort and effectiveness, reducing the likelihood of skin damage and promoting consistent handwashing practices.
As step three of the handwashing process outlined in the Food Standards code, Food Handlers must use soap when washing hands. These cleaning agents work to break down and lift contaminants from the skin’s surface and prevent the spread of dangerous microorganisms. Warm water aids in the emulsification of detergents, enhancing their ability to effectively remove dirt from the hands.
When cold water is used, detergents may not function optimally, leaving behind residue or contaminants. In contrast, warm water promotes the thorough distribution of detergents, ensuring that they can effectively lift and wash away potential sources of contamination. This is particularly crucial in food settings where even the smallest remnants of contaminants can lead to foodborne illnesses.
The use of warm water for handwashing is a crucial component of effective contamination prevention. It promotes comfortable and extended handwashing, reduces the risk of skin damage, and enhances the performance of detergents in removing contaminants.
Businesses operating in the food industry must prioritise the use of warm water in handwashing practices to safeguard public health, uphold food safety standards, and mitigate the risk of foodborne illnesses. By understanding the science behind handwashing and the role of water temperature, food establishments can take proactive measures to ensure the safety of both their consumers and their reputation in the industry.
