What is African swine fever
African swine fever (ASF) is an acute, hot and highly contagious animal infectious disease of pigs caused by ASF virus. Pigs are mainly infected by contact with virus or pollutants or by the bite of infected ticks. The incubation period is 15 days. OIE has listed it as a statutory reported animal epidemic disease, and China has listed it as a class of animal epidemic disease, which is a key foreign disease for prevention and control. African swine fever is not zoonotic and does not infect people. In recent years, African swine fever continues to be prevalent in Russia and Eastern European countries, but no cases have been reported in China.
What's the harm of eating hog cholera meat carelessly
Classical swine fever itself is not contagious. However, the systemic resistance of pigs suffering from classical swine fever is low, and their muscles and viscera are often accompanied by secondary infection of Salmonella. Eating such pork is easy to cause Salmonella food poisoning.
The incubation period of Salmonella food poisoning is the shortest 2 hours, and the elderly can reach 72 hours, with an average of 12-24 hours. There are mainly three types of manifestations, namely, gastrointestinal type, typhoid type and septicemia type. Gastrointestinal type is the most common. The precursor symptoms were chills, headache, dizziness, nausea and spasmodic abdominal pain, followed by vomiting, diarrhea, general pain or fever. Diarrhea can reach 7-8 times a day. The body temperature is between 38-40 ℃, the course of disease is about 3-5 days, diarrhea stops in 2-3 days generally, the body temperature returns to normal, and the general situation improves. Severe cases, especially children, the elderly and the infirm, are often life-threatening due to dehydration, acidosis, anuria, heart failure, etc.
