How long to keep food in the fridge
If I cooked that pasta on Tuesday, is it still good to eat tonight — or does it belong in the bin?
It pays to know a few rules when considering how long to keep food in your fridge. It all depends on the food, but according to microbiologist Professor Dirk Bockmuehl, most things will probably only keep for a few days.
Pasta and noodles should only be kept for three or four days, cooked potatoes are good for only three and cooked rice even only really keeps for two days. This is because these foods contain starch, which is very prone to attracting bacteria.
These bacteria also can’t easily be killed off by heating the food up, as they are very heat resistant. The microbiologist also recommends not keeping opened milk for longer than three or four days.
To prevent germs from accompanying your food into the fridge in the first place, make sure to put your cooled food in as soon as possible, two hours after cooking at the latest. Otherwise you increase the likelihood that the bacteria have quickly multiplied.
When reheating a meal, make sure to do so for at least two minutes at around 70 degrees Celsius. Bockmuehl also recommends you clean out your fridge at least once a month. – dpa
