I try to be good at this as I feel it is so important, especially with a little one in the house. I use separate chopping boards for meat, veg and bread.
I always use gloves when handling raw meat and discard with the food packaging immediately after use. Knives that have chopped chicken etc are put straight in the wash. I won't use the same one on the food once it's started cooking.
Raw egg is another thing I'm meticulous about, wiping away any spillage and washing hands as soon as it's been used.
I try and organise the fridge the best I can, though some tips might be good! Seperate drawer for meat, and one for veg, the rest doesn't really have any rules though.
Always clean down surfaces after handling food and wash hands thoroughly.
