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.
Keep your freezer at zero degrees (0Â°) or below to maintain the quality of frozen foods. Most foods will maintain good quality longer if the freezer temperature is -10 to -20Â°F.At temperatures between 0 and 32Â°F, food deteriorates more rapidly.Fluctuating temperatures, such as those in self-defrosting freezers, also may damage food quality.f your freezer does not have a built-in thermometer, check the temperature frequently. 1  One easy way to estimate the freezer's temperature is to check the consistency of ice cream stored inside the compartment. 2  If the ice cream is not brick-hard, the temperature of your freezer is too warm.
