A virulent strain of coliform E.coli has been found in Europe which produces a toxin named as “Shiga toxin” which leads to Haemolytic Uremic Syndrome(HUS) , a kind of kidney failure caused due to consumption of contaminated food. It is reported that 1700 people got infected by this disease over 12 European countries.
E.coli are nonspore forming facultative anaerobes which are commonly found in the gastrointestinal tract of the human.This specific group of E.coli named as STEC .They generally spread through supply water contaminated by cattle feces ,sewages .May also spread by unpasteurized milk, unblanched vegetables. The “Shiga toxin” produced by it first binds to the terminal galactose residue of glycolipid in the cell membrane which acts as a receptor and then it blocks ribosome functioning leading to interruption in protein synthesis.It affects the cells such as epithelial cells,cuboidal cells,tubular cells,macrophages present in the lower gastrointestinal tract. Related disease symptoms include severe diarrhea, lower abdominal pain, and nausea.
In order to keep it away from India ,preventive measures have been taken by Food Safety and Standards Authority of India(FSSAI) . It has been noticed to the major ports such as Kolkata , Haldia , Mumbai , Chennai and airports to keep watch on all the food items being imported from European countries. An order have been passed to the officials to keep record of all the agro based food commodities being transported to India from Europe which will be first tested in FSSAI lab before its entry in market. According to CEO of FSSAI Dr. V.N Gaur, no food commodity has been transported to India in last five months from European countries and if there is any import then they are all set to manage the situation.
Many of the countries have imposed a ban on import of affected food items from the countries like Germany , Spain, Denmark , France , Norway. According to WHO, certain changes in the traits of E.coli is the main cause behind the secretion of such infectious toxins. It is renal failure in juveniles.It may lead to neurological disorders such as coma,epilepsy, multiple sclerosis.
