Toxoplasma gondii infection occurs in humans and animals all over the world. The survey of 3/kloc-0 provinces, autonomous regions and municipalities in 200012004 showed that the positive rate of Toxoplasma gondii was about 8%, and the infection rate in the western region was higher than that in the eastern region. Lower than Anglo-American law (ranging from 16% to 90%). However, Toxoplasma infection has not attracted people's attention, and even clinicians have not noticed it. Because most people or animals infected with Toxoplasma gondii have no clinical symptoms, or the symptoms are very mild, they do not attract attention and do not receive treatment. Although these people or animals are not sick, they can be used as? Operator? Or the source of infection, leading to more infections. Only a few infected people are unfortunate. They have fever, fatigue, headache, muscle joint pain and other symptoms. When they were first infected. Generally speaking, the human body will develop immunity and heal itself (but Toxoplasma gondii cysts still exist in the body for a long time). After that, even if you are infected again, these symptoms will not appear. Therefore, it is difficult to find or confirm these cases unless the condition is particularly serious. Almost all the confirmed cases are patients with severe immunodeficiency.
However, if you conclude that Toxoplasma infection seems insignificant, you are wrong. Toxoplasma gondii infection during pregnancy can cause fetal infection, which may (the probability of early pregnancy is 40%, higher than the third trimester) or (the probability is unknown, but low) cause serious problems such as abortion, stillbirth and deformity. Therefore, pregnant women should pay attention to Toxoplasma gondii infection, especially in the first trimester, and the probability of Toxoplasma gondii infection causing serious fetal problems in the third trimester is very low (less than 3%). In addition, some research reports that if pregnant women are infected before pregnancy (acquired immunity), there is no chance to infect the fetus.
Obviously, the spread of Toxoplasma gondii in hot pot requires two conditions at the same time: first, the meat is contaminated by Toxoplasma gondii; Second, Toxoplasma gondii has not been killed. Animals are more likely to be infected with Toxoplasma gondii. For example, according to the survey, the infection rate of Toxoplasma gondii in sheep is about 6 1.4%. Toxoplasma gondii is mainly parasitic in muscles and internal organs, so the probability of Toxoplasma gondii in meat is high. In short, eating raw meat means a greater risk of infection. In fact, the health risks of eating raw meat are not limited to Toxoplasma gondii. Eating raw meat can infect various parasites, such as tapeworms, nematodes and trematodes, as well as bacteria and viruses.
Hot pot is good, but you can't be too greedy. If you let your friends eat for a few hours, it will not only make the stomach rest bad, but also cause inflammation and discomfort, and the baby will not have a good growth environment. In addition, the longer the soup is stewed, the less nutrition, and the nitrite will surge, which is not good for the fetus after intake.
