We had a power outage that lasted several days. After about 10 hours the food from the fridge and freezer (still cold/frozen as the doors had remained closed) was placed on the balcony, in plastic bags, and stayed there for 4 days. The temperatures throughout the whole time remained below 0, for most part way below 0. When we came back, all the food was frozen. Is it a good idea to keep all of it, or should some of it be discarded? I am particularly iffy about consuming the thawed milk and eggs. I'm also pregnant, so more susceptible to potential food poisoning.
