Hi, Everyone. (Excuse the paragraphs were there's a space between the lines. I can't figure out why it's doing that or how to correct it.) Does anyone know about the safety of freezing #5 Polypropylene (PP) food containers and whether any chemicals would leach into the food from it being at a freezing temperature? If it does leach, how bad would it be for me to eat the food anyways just this one time (approximately 90 ounces of food)? I bought some greek yogurt last night. My little fridge was having a hard time keeping it cold enough. I turned it up and stayed up very late waiting cause I wanted to adjust it once cold enough so it wouldn't freeze. It's hard to know how much to adjust it, I woke up this morning it was frozen. I had this happen with other kinds of containers. I called those container's company and they said I need to throw it away cause the lining will wasn't made for that cold of a temperature and the chemicals would leach into the food. I'm not concerned about the yogurt being safe from being frozen, I'm concerned about it being safe from the container chemicals leaching into my yogurt from being frozen. I phoned the yogurt company. They only had a script, really didn't know the answer about freezing, and had no one else to transfer me too that would have more knowledge. I've googled many different ways and can't find anything specific enough by a source that would be more reputable about the safety of this. I would just throw it away except for the cost, I'm out of bread and I now have nothing to eat... I've already had to throw out $8 worth of food last week and this would be another $13. This is bad. Does anyone have any knowledge about the safety of freezing #5 Polypropylene (PP) food containers and whether any chemicals would leach into the food from it being at a freezing temperature? And if it does leach, how bad would it be for me to eat the food anyways just this time - about 90 ounces of food? Thank you. I hope somebody knows more about this. Fingers crossed.
