I have two pounds of hamburger in my refrigerator that are about three days old. They started out frozen so I figure it took a day to thaw. Is it safe to use?
Microwave a frozen hamburger for at least 2-3 minutes per side to ensure it is cooked thoroughly and safe to eat. Use a food thermometer to check that the internal temperature reaches 160F (71C).
To thaw frozen hamburger effectively, place it in the refrigerator overnight or use the defrost setting on the microwave. Avoid thawing at room temperature to prevent bacteria growth.
If it still has crystals on it, it is good. When the electricity goes out for a short time, it makes no difference as long as you keep the door shut. If you have had a storm, stuff the freezer so that there are no spaces and then keep the door closed. It should keep things frozen for a few days. At last gasp, ask the neighbors over for barbeque!
Some creative and delicious frozen hamburger recipes to try are stuffed burgers with cheese and bacon, teriyaki pineapple burgers, and spicy sriracha burgers.
Vacuum sealed hamburger meat that is frozen can last 2 to 3 months. When it is thawed, it shouldn't be kept in the refrigerator more than a couple days.
