E.coli - What's it?



I hope all reader are aware of lately one of the hottest topic of food is E.coli. A large exposure in Germany on  E.coli bacteria infection through raw vegetables (the first trace of the root of infection is cucumber and now is confirmed from bean sprouts sources grown on a farm in northern Germany). It is being suspected the reason behind is due to contaminated water that use for bean sprouts as water supply. Germany Robert Koch Institute (RKI) has announced that contaminated bean sprouts were the source of the outbreak. Travelers should aware that the recommendation not to eat cucumbers, tomatoes and leafy salads.
I took some time to study these kind of case before sharing on my blog. The specific E.coli strains that cause outbreaks of disease in this incident are named as E.coli 0104:H4. Patients may experienced hemorrhagic colitis (inflammation and bleeding of the colon). Let's know what can E.coli cause, EHEC and HUS. EHEC 
is refer as Hemorrhagic (bloody) diarrhea: an increased amount of blood in the diarrheal stool that doesn't
resolve and is usually accompanied by severe abdominal pain. Although this may resolve within a week, some individuals can develop anemia and dehydration that can cause death. Hemolytic-uremic syndrome (HUS) : symptoms of pallor (due to anemia), fever, bruising or nose bleeding, fatigue, shortness of breath, swelling of the body, especially hands and feet, jaundice, and reduced flow of urine may be seen. HUS symptoms usually develop about 7 to 10 days after the initial diarrhea begins. HUS is the most common cause of kidney failure in children that damage the kidneys and destroys platelets which can lead to kidney failure, excessive bleeding, seizures or death.
Prevention includes eating well cooked foods, and drinking treated or pasteurized fluids. Avoiding touching or eating any food that may be contaminated with any animal or human waste will help to prevent the infection too. When you are preparing any fresh produce, begin with clean hands. Wash the produce under running water just before preparing or eating. This includes produce that grown conventionally or organically at home, or produce that is purchased from a grocery store or farmer's market.
Furthermore, proper storage of fresh produce can affect both quality and safety. Certain perishable fresh fruits and vegetables (like strawberries, lettuce, herbs, and mushrooms) can be best maintained by storing in a clean refrigerator at a temperature of 40° F or below. All produce that is purchased pre-cut or peeled should be refrigerated to maintain both quality and safety.

Folks, prevention is better than cure. Do practice a good hygiene as a first step to good health. Cheers.

最近在德国有一个关于蔬菜类被大肠杆菌种类的细菌感染(一开始被怀疑的是黄瓜,现在证实了豆芽)。这是因为怀疑受污染的水被作为豆芽的水源。德国罗伯特科赫研究所(RKI)日前宣布,受污染的豆芽是此次感染爆发的根源。德国公众卫生当局目前建议,劝人们不要吃生豆芽。建议不吃黄瓜,西红柿和绿叶沙拉在德国北部已在610日解除
诊断是通过发现大肠杆菌病在粪便里。大多数大肠杆菌感染的解决是自发的,不需要治疗。但是,如果病人变得脱水,贫血(血损失过多,由于出血性腹泻),密切的治疗是需要
我翻查了一些资料。使疾病暴发的大肠杆菌在这一事件被称为的大肠杆菌0104H4。有些患者经历(炎症和结肠出血)​​出血性结肠炎。此类大肠杆菌会出现在受污染的水,食物和未经高温消毒或不正确消毒(热处理)乳制品等。一个人可能会被污染一旦接触到的带菌者,受污染的食物或液体

预防此类细菌包括吃煮熟的食物,饮用处理或消毒了的干净水。避免接触或食用任何可能与受感染的动物或人类粪便接触
正确的新鲜农产品储存,可影响质量和安全。某些易腐新鲜水果和蔬菜(如草莓,生菜,草药和蘑菇)最能维持在一个干净的冰箱储存在一个40 ° F或以下的温度。如果你不能确定是否应冷藏为维护品质,在还未买时请您询问详情。所有购买预先切开或去皮的食物应该冷藏以维持质量和安全
