Importance of Hand Hygiene in the Food Industry
Hand hygiene is vital for food handlers in the food processing, hospitality and food service sectors, and is a legal requirement under the Food Safety Standards (Food Standards Australia New Zealand 2018). If hand washing practices are not effectively implemented, harmful germs can be transmitted to food contact surfaces and from food handling, resulting in possible contamination.
With the World Health Organisation (2006) identifying over 200 diseases that can be transmitted through food, it’s important to minimise the risk of foodborne illnesses. Hand washing facilities should be conveniently located in food preparation areas and bathrooms. As reported by Food Standards Australia New Zealand (2018), food handlers must take care in their health and hygiene and report symptoms of food poisoning, such as stomach pains, vomiting and diarrhoea, to their supervisor. Immediate action and appropriate conduct by all staff in the food environment is the best strategy in preventing food contamination.
Implementing Food Safety and Hand Hygiene Practices
Routine hand washing is crucial for food handlers, food production and processing employees. According to Roberts (2015), food safety depends significantly on the hands-on approach and accountability of staff towards hand cleanliness by upholding a rigorous hand hygiene regime.
The World Health Organisation (2006), Food Standards Australia New Zealand (2018) and NSW Food Authority (2018), all recommend that hand hygiene should occur in the following situations as best practice:
1. Before commencing food handling and during different stages of food preparation, for example switching from handling raw meat to working with cooked food. To help prevent cross contamination, use separate equipment and utensils when preparing and storing raw food and cooked food.
2. Before donning and after doffing certified food-safe disposable gloves. Ensure hands are properly cleaned and dried.
3. After taking comfort breaks, such as eating lunch or using the toilet facilities, it is vital to wash and sanitise hands to prevent contamination with faecal bacteria.
4. After respiratory behaviours such as coughing or sneezing, in addition to touching any area of your face or head, such as using a tissue to blow your nose. It is important to cover your face when sneezing or coughing, to reduce the spread of germs.
5. After cleaning activities, such as handling food waste or cleaning chemicals.
Hand Hygiene Technique for Food Industry Professionals
Food industry professionals are expected to perform proper hand washing procedures to ensure that their hands are clean and safe to use for food handling, preparation, production, and serving.
The NSW Food Authority (2018) has created the following step-by-step process for effective hand washing:
1. Wash hands methodically with plain or anti-microbial soap and clean, warm, running water.
2. Soap hands together, lathering well to cover all surfaces (back hand, between fingers, under nails).
3. Scrub hands together for a minimum of 20 seconds.
4. Cleanse hands under clean, warm, running water until all the soap is removed.
5. Dry hands thoroughly with a clean single-use paper towel or under a hand dryer if available.
