Here are 10 food safety facts that you may have not known (part Ⅱ)

6. The best way to know if the milk is still good is to smell it

Experts say that if you keep your fridge closer to 34℉, instead of the standard 40℉, you can get an extra week out of your milk. Of course, the longer its container was kept sealed, the better. All in all, it's always best to trust your good old nose and just smell the stuff.

7. A funky taste in water doesn't mean you can't drink it

Ever left a glass of water sitting on the bedside overnight and then it had that funky taste in the morning? Well, turns out it's perfectly fine to drink. Duh—after all, there are no ingredients in the water that would make it go bad.

8. Produce bins in fridges are full of germs

A NSF International study found that the fridge produce compartment is one of the most "germiest" areas in people's kitchens. Therefore, it's essential to regularly clean out produce bins with hot water and liquid soap to prevent the buildup of bacteria.

9. Chopping boards are up to 200 times dirtier than a toilet seat

It has been found that chopping boards are up to 200 times dirtier than a toilet seat! And as it turns out, washing it after every use does not protect you from all the bacteria. It is recommended to have several chopping boards so you can use them for different types of food. In addition to this, you should change your chopping boards regularly as bacteria can hide in its scratches and crevices and thus contaminate other foods.

10. It's not recommended to rinse meat

While some people rinse meat and poultry before cooking, it turns out that while it can remove some of the bacteria from the surface, it doesn't do anything to those that are tightly attached. In addition to this, water can splash while rinsing meat onto worktops, cutlery, etc., and thus contaminate them.
