Had a couple bags of frozen blueberries. Put them in the fridge to thaw. They've been in the fridge for several weeks. Can I still cook with them?

I strongly believe it's no good any more.

Update after hearing some comments [2nd update]

When u see liquid in the bag, it means the temp is usually above zero C which means it isn't the ideal temp for frozen berries.

I think it's usually quite ok to keep in the fridge for a few days, but not weeks

[3rd update] I am sorry for whatever confused I caused and I removed the comments about liquid in my previous answer to avoid confusion when people see this post in the future. Anyway, I found a box of forzen berries and here is what the pack suggests.

Please don't eat the berries if they are in the fridge for more than a few days

    I don't know if I agree with this. Depending on how well they were kept frozen, there could very well be an accumulation of juice when they thaw even if they are perfectly good. – Sobachatina Nov 5 '10 at 13:13
  • @Sobachatina: Agreed, even with the most careful home freezing, you're going to have some ruptured cell walls which leads to liquid loss when you thaw, no matter what you do. – stephennmcdonald Nov 5 '10 at 13:30
  • But the original post said it was in the fridge for weeks, so I cannot see how it's still good – Foodrules Nov 5 '10 at 13:46

    @Foodrules - To be clear- I agree with you that they are probably not still good. I objected only to the statement that liquid in the bag would indicate that they are bad. – Sobachatina Nov 5 '10 at 13:49
  • Sorry I kept missing about explaining why liquid is such a big deal here. When u see liquid in the bag, it means the temp is usually above zero C which means it isn't the ideal temp for frozen berries. I think the package of frozen berries asks to keep it below -4 C at most. Therefore, liquid in the bag is such a big deal. – Foodrules Nov 5 '10 at 13:58

Trust your nose.

But I suspect they will be long dead - fermented/rotted

  • Although they would contain some quote un-quote "poison" in the form of alcohol, is used to sterilize things, and it's well known that some of the most nutritious foods are fermented foods - kimchi is one of the best sources of vitamin K, and only fermented foods have vitamin K. All sorts of people take probiotics. Is the bacteria bad? Not in my book. Let's see if I'm alive tomorrow... (Edit: WOW my berries have fermented a lot more since last time I had them. The alcohol taste is strong.) – Devin G Rhode May 24 '18 at 19:38
