Most of us get food poisoning at some point in our lives. But while most people recover fairly quickly, food poisoning can be downright dangerous, particularly for the vast number of Australians who fall into the “most vulnerable” group: unborn babies, young children, seniors, and people with poor immunity.
To prevent food poisoning, it’s important to always handle food with great care. This includes keeping a close eye on the food in your fridge, and throwing things out as soon as they may no longer be safe.
We share a few important guidelines:
Upper and middle shelves
The upper and middle shelves are suitable for dairy products, spreads, sauces, cream, leftovers and cooked food, as well as opened mayonnaise, mustard and tomato-sauce containers.
Storage guidelines:
• Soups and stews containing meat: three to four days
• Leftover pizza: three days
• Salad dressing without preservatives: one week and with preservatives: one month
• Margarine: three months
• Cooked salads that contain mayonnaise: three to five days. If left at room temperature bacteria will flourish.
• Fresh mixed salad: one day
• Raw or leftover chicken: one to two days
• Mayonnaise, tomato sauce and chutney: two months after being opened
Bottom shelf
Keep fresh meat on the bottom shelf or in a container to prevent meat juices from dripping on and contaminating other food. Animal protein spoils more easily and quickly than other foods. Keep meat as cool as possible and place it as far back in the fridge as you can.
Storage guidelines:
• Raw or cooked fish: one to two days
• Mince: one to two days
• Ham: one to three weeks in a sealed container or until the expiry date, whichever comes first
• Cooked leftover meat such as leg of lamb: two days
• Whole, unpeeled fruit and vegetables (except bananas, unripe avocados, pumpkin, whole garlic cloves, potatoes and onions): no longer than a week
The fridge door
The fridge door is perfect for storing smaller items like eggs, cheese, sauces, milk, juice and nuts, and medicines.
Storage guidelines:
• Fresh eggs: two to three weeks; hard-boiled eggs: one week
• Cheese: soft cheeses: seven days; cream cheese: two weeks; cheddar and sweetmilk: one month; parmesan: six months
• Vienna sausages: one week in a sealed container in the fridge or until the expiry date
• Nuts and seeds: up to three months
• Milk and fruit juice: five to seven days, or until the expiry date
• Keep medicines in the door if they need to be refrigerated.
A few essential tips
Keep your food as fresh as possible with these important fridge tips:
• The ideal temperature inside a fridge is more or less 4° Celsius. The freezer compartment, on the other hand, should be about -15° Celsius. Remember to adjust the fridge temperature as the weather gets warmer.
• Don’t open the fridge door unnecessarily or leave it open. The fridge should also not be close to the stove or in a sunny spot in the kitchen.
• Wash your fridge every two weeks with a weak solution of bleach and water.
• Keep fresh food at the back of the fridge and try to use older food first.
• Clean up anything that spills immediately.
• Don’t overfill your fridge; it interferes with the airflow.
• Look out for the following signs of danger:
- Food changing colour or becoming mouldy
- A slimy film on cold meat
- Any strange smells or peculiar tastes
- Lids popping off plastic containers
