My mum has put the fear of cooking/freezing into me with an email this morning. She was reminding me to check the thermostat on my fridge and freezer regularly. She wrote “How cold is your fridge? And how cold does the freezer get? You know it has to be at least minus 15 in order to keep commercially frozen foods frozen safely? And you can’t actually freeze thing yourself because you need minus 30. If you put leftovers or whatever in the freezer, you will get about 200 bacteria being cultivated in it.”
So I was hoping you might be able to get some answers from other mother-experts out there on safe fridge/freezer practices. Thank you!

  • Ok first your mom is wrong about freezing things – all food put into the freezer will get down to the temp it is set on so don’t worry – QLD health says this for temps – Check the inside temperatures of your fridge and freezer. Fridges should be between 3°C and 5°C and freezers between -15°C and -18°C.

  • As far as I knew so long as it was completely cool before fridging or freezing with no condensation on the lid in an air tight container or bag it was fine.
    Only rule I’ve ever followed (other than those common sense ones) is: If it’s been frozen raw and then defrosted even a little cook it before refreezing, and if it’s cooked and been defrosted eat it that day.
    Oh and I never freeze rice – but then I never put rice in the fridge either – a little known fact is that most cases of food poisoning occur not from chicken or meat as is commonly believed but rice – because when rice goes bad it doesn’t smell look or taste any different – until it goes really bad and then it gets that pink weird crap growing on it. So I am always better safe than sorry with rice. :) But I freeze pretty much anything else.

  • I pre prepare meals every weeks and freeze them. We have never had an issue. My freezer is set to -24. I’ve never heard that you have to have a certain temp that differs for different foods. I always thought that deep freeze was -18 I set mine colder cause the sun comes in the window next to the freezer.

  • I’ve been freezing leftovers forever and never had an issue. Including prepared baby foods.

  • I freeze left overs and have never had an issue. Make sure you don’t put it in hot or warm and you should be fine

  • i was told to always put bubs food straight into the freezer even if hot. to stop ay bacteria forming or producing

  • If you heat it to piping hot doesn’t it then kill most of the bacteria? We don’t often have leftovers to freeze but when we have done we haven’t gotten sick from it.

  • Ive never had a problem freezing meals =/

  • I have absolutely no idea never even thought of it.

  • common sense rules! if you can no longer tell what it is/was, best not to eat it. If you have recently frozen it – should be fine. I have been cooking and freezing my own food for many years, and I have never had a problem, despite what must be multitudes of bacteria, as my freezer is certainly not at -30!!!

  • I always thought that as long as it is reheated properly and thoroughly then that kills any bugs that may have infiltrated during the freezing process! Food should be piping hot to serve.

  • I’m not sure but will need to find out soon.

  • wow im not sure bout thiz one but it has got me thinking i should find out bout it too.

  • Hope that helps out, good luck :-)
