One severe complication associated with E. coli infection is hemolytic uremic syndrome (HUS). The infection produces toxic substances that destroy red blood cells, causing kidney injury. HUS can require intensive care, kidney dialysis, and transfusions.
All freezers should be in the 0 to 8 degrees Fahrenheit (approximately -18 degrees to -13 degrees Celsius) range. However, when you first turn on the freezer, or put a lot of food into it, it may take up to 24 hours for the freezer to reach this temperature range.
Answer: You should keep your freezer temperature at or below 0Â° F, says the U.S. Food and Drug Administration. At that freezer temperature, the growth of harmful bacteria will be halted â indeed, foods that are kept constantly frozen at 0Â°F or lower will keep safe indefinitely, notes the FDA. The best way to find out whether your freezer is cold enough is to use a freezer thermometer. You can find inexpensive models at most grocery and hardware stores.
