The Facts About EHEC

Abgelegt in food

E.Coli is a bacteria found in warm-blooded mammals. EHEC is the enterohaemmorrhagic strain that causes food-borne disease. EHEC is transmitted through fecal contamination and grows at temperatures between 44.6-122?. EHEC E coli symptoms include abdominal cramping and diarrhea. Occasionally, diarrhea may escalate to a bloody diarrhea, called hemorrhagic colitis. EHEC bacteria may also cause fever and vomiting.

EHEC E coli incubates for 3-8 days, recovery takes around 10 days. In rare cases, hemolytic uremic syndrome (HUS) may occur. HUS occurs in approximately 10% of cases, with 3-5% proving fatal. HUS causes acute kidney failure, hemolytic anemia, and thrombocytopenia.

Several causes for EHEC found
EHEC occurs when bacteria-infected feces contaminates food or water, or cross-contamination occurs between contaminated food sources and cooking surfaces. Common sources of EHEC E coli include undercooked meats, raw milk, sprouts, lettuce, tomatoes, and water. This list is far from exhaustive.

Prevention against EHEC
Antibiotics are ineffective and may aggravate kidney problems while contributing to antibiotic resistance. To lessen bacteria contamination, preventative measures are needed at all stages of food production. From educating workers in hygienic practices, to proper food preparation and storage, contamination may be lessened.

Screening animals before slaughter could also help. So can bacterial treatment, namely cooking, pasteurization, or irradiation. Also, checking the purity of water sources is important. In food preparation, sanitation is imperative, as are safe food temperatures. Cold foods should be below 39.2?, while hot foods should be above 149?.

Uncooked produce present additional problems. Especially sprouts, linked with many outbreaks. These sprouts may become contaminated from the transportation, storage, or harvesting stages of the seeds. For all fruits and vegetables, hygienic practices are crucial. When possible, produce should be grown away from potential sources of contamination. This includes protective measures from animals or stored manure. The use of manure should also be limited or avoided.
