Food hygiene involves handling, preparing, and storing food safely to prevent contamination and foodborne illnesses. Proper hygiene practices help ensure that food remains safe to consume and nutritious. This lesson explains important food hygiene concepts, which will help students develop critical thinking and a deep understanding of why each practice is essential.

Importance of Proper Food Storage

Let's understand the importance of proper food storage: 

Storing Dairy Products Correctly

Dairy products like milk, yogurt, and cheese spoil quickly if not stored properly. Milk and dairy must be refrigerated at temperatures between 0 and 4 degrees Celsius. Bacteria multiply rapidly at room temperature, causing dairy products to become unsafe. Refrigeration slows bacterial growth, extending shelf life and ensuring safety.

Why Refrigeration is Important:

• Bacteria need warmth to grow. Cold temperatures slow their multiplication.
• Keeping dairy products refrigerated maintains their freshness and nutritional value.

Avoiding Risky Foods for Older Adults

Older individuals have weaker immune systems, increasing their vulnerability to foodborne illnesses like listeriosis. Ripened soft cheeses (e.g., Brie, Camembert) can harbor harmful bacteria such as Listeria, which thrive in moist environments. Older people should avoid these cheeses to prevent health complications.

What Foods Should Be Avoided by At-Risk Groups?

Certain foods pose higher risks of bacterial contamination:

• Raw shellfish: Often contaminated with pathogens from water.
• Pâté: Can contain Listeria.
• Partially cooked eggs: Risk of Salmonella.

At-risk individuals include children, the elderly, pregnant women, and those with compromised immune systems. Avoiding these foods significantly reduces their risk of severe foodborne illnesses.

Preventing Direct Food Contamination

Direct contamination occurs when harmful substances or microorganisms come into contact with food directly, making it unsafe.

Strategies to Prevent Contamination

• Cover Food: Always keep food covered to protect it from airborne contaminants, pests, and accidental spills.
• Separate Raw and Cooked Foods: Prevent cross-contamination by storing raw foods below cooked foods in refrigerators.
• Wash Hands Thoroughly: Always wash hands for at least 20 seconds with soap and warm water before handling food.
• Use Colour-Coded Equipment: Different utensils and cutting boards for raw meats and vegetables prevent bacterial transfer.
• Clean Spillages Immediately: Quickly wiping up spillages prevents accidental contamination.

Cross-Contamination

Cross-contamination is when bacteria transfer from raw foods to cooked or ready-to-eat foods. Proper separation of foods and equipment helps prevent this. Students should understand the importance of thorough cleaning after handling raw meat.

How to Manage Cuts and Wounds

Covering Cuts Properly

Open wounds and cuts can harbor and spread harmful bacteria, contaminating food easily. Cover all wounds with a blue waterproof plaster, which is clearly visible if accidentally lost in food, ensuring it is removed promptly.

Importance of Blue Waterproof Plasters

• The blue color makes them easy to spot.
• Waterproof barriers prevent bacteria and moisture from entering wounds.
• Reduces risk of infection and food contamination.

Guidelines for Food Safety

Here are some guidelines for food safety: 

Essential Food Hygiene Practices

• Cleanliness: Regularly clean kitchen surfaces, utensils, and hands thoroughly.
• Cooking Temperatures: Ensure foods are cooked to recommended internal temperatures. Using a food thermometer can help verify this.
• Chilling Food Quickly: Place perishable food in refrigerators within two hours to prevent bacterial growth.
• Monitoring Expiry Dates: Consuming foods before expiration dates ensures freshness and reduces contamination risks.

Useful Kitchen Cleanliness Practices

Students should understand the following practical cleanliness steps:

• Use hot, soapy water to clean surfaces after food preparation.
• Replace cleaning cloths and towels frequently.
• Regularly sanitize surfaces to minimize bacteria.
