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.
While many foods will freeze at about 32Â° Fahrenheit, they need to be stored at 0Â° Fahrenheit to slow down deterioration, so colder is better. And don't worry about freezer burn with really cold temperatures â it's caused by exposure to air, not temperature.
