-20°C can still survive for one year!
Be wary of the "cold killer" listeria
Listeria monocytogenes, a strain widely found in nature, is the main pathogen causing foodborne disease outbreaks and one of the deadly foodborne pathogens, with a case fatality rate of 20%~50%. Listeria monocytogenes can still grow and reproduce in a refrigerated environment of 0~4 °C, and can survive for 1 year in a low temperature environment of -20 °C.
Raw milk sources and their products, ice cream, raw fruits and vegetables, meat and meat products, cold cooked raw foods, smoked seafood, etc., are all foods that are easily contaminated by Listeria monocytogenes.
These populations
It is a key "target" of Listeria monocytogenes
In healthy adults, Listeria monocytogenes has limited pathogenicity, usually with diarrhea, nausea, vomiting, fever, headache, and muscle pain 3 to 70 days (usually 21 days) after eating food contaminated with Listeria monocytogenes.
Pregnant women, infants, the elderly, cancer patients and other immunocompromised people are the key targets of listeria attacks.
The elderly and people with low immunity may be infected with sepsis, meningitis, etc., which can be fatal in severe cases.
After pregnant women are infected, Listeria monocytogenes can infect the fetus through the placenta and birth canal, and in severe cases, it will lead to miscarriage, stillbirth, premature birth, neonatal sepsis, etc., and the mortality rate of neonatal infection is as high as 30%~70%.
Listeria monocytogenes is very "afraid of heat"
Use these few tricks against it
Don't look at the "vitality" of Listeria monocytogenes so tenacious, but it has a fatal weakness - "fear of heat". Cooking it thoroughly is a simple measure to deal with it.
Clean the refrigerator regularly to avoid the growth of various bacteria; Before putting food in the refrigerator, it should be sealed and separated from raw and cooked.
Raw and cold food taken out of the refrigerator should be heated at 60°C for 20 minutes, or 70°C for more than 5 minutes before eating.
Avoid eating raw vegetables and meat without any pasteurisation, and cook eggs, meats and seafood thoroughly cooked.
Hands, knives and cutting boards should be cleaned after contact with raw food.
Fruits should be washed thoroughly before eating, and it is best to peel them before eating. When buying ready-to-eat food, check that the food packaging seal is intact.
The refrigerator is not a "safe" for food

Before eating leftovers from the refrigerator
Be sure to heat it adequately
