Summer surely is a lot of food lovers carnival season, vegetables, fruits and seafood a lot of the season, came into all kinds of snack street food festival, and at night in major cities, many people will choose at this time to meet their own appetites. But enjoy the food on the occasion, will also take advantage of a variety of food-borne infectious diseases, made some careless eaters "caught." So enjoy apart, may wish to look at the prevention of "disease from the mouth" approach, the maximum to avoid contracting foodborne illness.
Unclean food: hepatitis A, typhoid fever and hepatitis E
Ubiquitous food stalls, small restaurants, a lot of people dining options. But once selected dining places can not guarantee food processing and transportation of sanitation, it is possible to lead to food by the faecal - oral route being contaminated by pathogens (ie fecal contamination with pathogens the water, the water then contaminate food) and the spread of disease. In China, more common by the faecal - oral transmission of infectious diseases in three ways: Hepatitis A, Hepatitis A and typhoid fever.
Hepatitis A: (HAV) is caused by the hepatitis A virus, in Shanghai in 1988 had triggered a global pandemic famous (Shanghai citizens was due to eating the clam containing the outbreak of HAV), causing more than 290,000 people infected with HAV. Fruit, shellfish and meat easily contaminated, there had developed due to imported contaminated mangosteen, strawberries and other fruits caused small outbreaks of experience. Acute hepatitis symptoms are often mild, even in children showed only do not cause symptoms or gastroenteritis. The pre-adult infection may have anorexia, nausea and other gastrointestinal symptoms, infection generally have jaundice (sclera, yellowing of the skin), pruritus (cholestasis performance) and liver dysfunction and other symptoms. Acute hepatitis A self-limiting, only symptomatic treatment is generally given to low-fat and high-carbohydrate diet, a small number of critically ill patients require hospitalization. Prevention of HAV vaccine has been in our country are routine vaccination, people coming to the area may also be eating unclean replant.
Hepatitis: caused by Hepatitis E virus (HEV), often with the virus after being infected by fecal contamination of water sources in the country few can not guarantee safety of drinking water in the mountains or pastoral, sometimes seen in acute hepatitis small outbreaks. Symptoms of acute hepatitis and acute hepatitis same, but pregnant women, HEV infection can cause life-threatening fulminant hepatitis. Acute hepatitis E have the same self-limiting, symptomatic treatment can be improved. China has more HEV vaccine to market, visiting the affected areas of optional vaccination.
Typhoid: from Salmonella typhi or Salmonella paratyphoid caused by acute bacterial infection mainly spread through a variety of transportation, processing and improper food Although rare in recent years, but there are still a lot of people sick. Mainly as a high fever accompanied by chills or chills, loss of appetite, sore throat, cough, fatigue, diarrhea and other symptoms. By dining out experience, disease manifestations and laboratory tests (such as bacterial culture and Widal), can confirm the diagnosis of typhoid fever. Although the diagnosis of the disease have a certain degree of difficulty, but the treatment is very simple, usually only to oral antibiotics.
Lamb and dairy: Brucellosis
Regardless of seasons, lamb are a lot of people loved the food, dairy, too. Some people in pursuit of "taste", "style", or worry about the market fake lamb, poor quality milk, may choose to purchase just the direct slaughter, extrusion without quarantine lamb or milk. But everyone knows, the quarantine has not been such food can spread easily from brucellosis, which cause additional troubles.
Brucella mainly parasitic in the body of cattle, sheep and other livestock, the main infection generally herders, livestock slaughter and milker, but due to recent purchase without quarantine lamb, dairy cases increase, also Brucella start infection ordinary people. Common acute brucellosis can cause fever, sweating, fatigue, headache and joint pain and other symptoms, especially joint pain is often more severe and generally ineffective treatment. For patients who had consumed without quarantine meat, dairy and produce similar symptoms, the doctor will arrange for Brucella agglutination test or bacterial culture to confirm the diagnosis. Like with typhoid fever, brucellosis good treatment, generally only a certain course of oral antibiotics can be cured. But if the diagnosis is not timely, or after illness prevention rather not pay attention to repeated infections, it is possible to cause permanent joint deformity and even joint pain.
Seafood and sashimi: anisakiasis
Summer has always been a popular seafood dishes, as a time when the fishing season, seafood tend to be very cheap, many people will choose at this time bites. But in recent years overseas incoming sashimi, but also by many people of all ages. But if you do not do a good job safety measures, it may be infected with Anisakis disease enjoy both delicious when serious or even fatal consequences.
Anisakis is a present in many marine animals (including fish and squid) parasites, in the consumption of undercooked animal parasite, it may be infected with Anisakis. If an ingestion of a lot of worms, it will lead to nausea, abdominal pain, vomiting and other symptoms of acute manifestations anisakis disease, but the disease is relatively rare. More often, the first ingestion of Anisakis parasite by the body identified as immunogen, when ingested parasites again, the immune system produces severe immune response against the parasitic worms and their organizations, causing fatal anaphylactic shock. Fortunately, the majority of countries, including my own for seafood has a strict quarantine measures and requirements may be used for raw seafood need to go through enough to kill parasites freezing measures, so after eating raw seafood is generally not quarantine infected with the disease. But in Japan, due to the need for "fresh" and "delicious", not about seafood freezing measures may need to be careful when eating sashimi in Japan.
Meat: neurocysticercosis
Compared to the above kinds of food, meat is more common in ordinary life, but also has a more important position. But seemingly insignificant meat, but it can spread a very serious parasitic disease - neurocysticercosis (NCC).
And very common parasitic infection as taeniasis, NCC pathogen is pork tapeworm. After the body itself by exogenous infection (taeniasis patients contaminated with tapeworm eggs hand, then through the mouth infection) or exogenous allograft infection (eating undercooked meat containing tapeworm, containing tapeworm eggs and vegetables) and tapeworm infection, tapeworms eggs hatch from larvae will spread via the blood circulation to the brain, concurrent bred cysticerci. Once the parasitic cysticerci in brain death, human death worm for experience severe immune response, resulting in severe local tissue inflammation, usually manifested as headache, seizures, increased intracranial pressure and other symptoms. Sometimes cysticerci also parasitic in the ventricle, when the patient will head sharply to block the circulation of cerebrospinal fluid in the ventricles for the hole, causing a sharp increase in intracranial pressure and sudden death. While worming treatment can cure the disease, but severe immune reaction worming itself has a high mortality rate, but also makes the disease very difficult to treat.
