小编摘要:细菌在低温下也能生存,塞满食物的冰箱危险重重,肉类不能放在顶层,奶酪蔬菜需小心,大米谷物不安全,鼻子也会不可靠……你知道冰箱到底该怎么用吗?

 导读:洁白凉爽的冰箱似乎是食物安全的庇护所。如果你这么想的话,你就要遇到麻烦了!研究表明,冰箱的沙拉抽屉含有的细菌数是安全标准的750倍之多,其中包括可能致命的大肠杆菌、沙门氏菌、李斯特杆菌等。食物烹煮不熟或交叉污染引起的食物中毒不可小觑,因此了解该如何储藏食物是预防食物中毒必不可少的一部分。那么到底该如何使用冰箱保护家人呢?一起来看看!

Gleaming white and perfectly cool, the kitchen fridge seems a safe haven for your food. But if you believe that, you may be in for a nasty surprise.

A study has revealed that refrigerator salad drawers can contain up to 750 times the level of bacteria considered safe, with potential killers such as E.Coli 0157, salmonella and listeria lurking in our fridges at much higher rates than previously suspected.

According to the Food Standards Agency, each year in the UK around a million people suffer a food-borne illness.

Twenty thousand of these receive hospital treatment and 500 die from food poisoning. It also costs the economy £1.5 billion a year. 

'The vast majority of food poisoning occurs because of under-cooking or cross contamination of food,’ says Professor Tom Humphrey of the Institute of Infection and Global Health at the University of Liverpool.

'Understanding food storage — and most fresh food is stored in the fridge — is integral to preventing food poisoning in your home.’

Here, we reveal the dangers hiding in your fridge, and how to protect yourself.

GERMS CAN SURVIVE COLD TEMPERATURES 

低温细菌也能生存

'Many people wrongly believe that chilling food kills off bacteria,’ says Professor Humphrey.

'All chilling does is slow down the rate of the multiplication of the bacteria, so that food which may have lasted only a few hours at room temperature can last a few days. Indeed, some bacteria aren’t slowed down in the fridge at all and thus are still very much a potential source of food poisoning. Listeria bacteria, commonly found in foods such as soft cheese, cold meats, pates and smoked fish, can grow quite well at a temperature range of -1C up to 4C.’

Listeria poisoning causes flu-like symptoms and, in rare cases, septicaemia or meningitis.

Most people do not keep their fridges at a cold enough temperature, says Prof Humphrey.

'The recommendations are 5C or less, but the average domestic fridge is set to 6C or above, as people are simply not aware of how cold they should be. Ideally, everybody should use a fridge thermometer and aim for a constant four degrees. Don’t leave the fridge door open for long, and never put hot food in the fridge, as this will also push the internal temperature back up.’

PERILS OF A PACKED FRIDGE

不要把冰箱塞得太满

We ask much more of our fridges now than we did even ten years ago, says Prof Humphrey.

'Our parents’ generation stored opened jars or jams, or ketchups, in cupboards, and because of the high content of preservatives in these items, that was perfectly safe. Now, food manufacturers are cutting back on preservatives in line with consumer demand and Government health guidelines and, as a result, these products are more likely to need to go into the fridge after they have been opened.’

A basic rule of fridge hygiene is, if you have a full fridge, turn down its thermostat to compensate.

Meanwhile, be sure to give your fridge a regular clean, says Prof Humphrey.

'Fridges need cleaning out once a week with very hot water and disinfectant if you wish, with the raw meat compartment being cleaned out every few days — certainly when it becomes smelly.’
