In November 1996 Scotland suffered an outbreak from a bacteria named Escherichia Coli 0157 that originated from meat products and contaminated steaks in a butcher’s shop in Wishaw Lanarkshire. The bacteria reproduced in such quantity that it became one of the most relevant epidemics in history with 256 infected and 16 dead.

The bacteria was first detected in the United States in 1982 where 47 people where infected from eating contaminated hamburgers.

The 0157:h7 is a rare variety of E.Coli that produces great amount of toxins that cause important damages on the intestinal mucus, diarrhea, vomiting and in the worst cases it produces Uremic Hemolytic Syndrome (UHS) which is the main cause of renal damage on children in the United States.

There are 10 to 20 thousand cases estimated to take place in the U.S. The bacteria has affected other countries such as Spain, Italy, Denmark, Germany and Japan where the latest outbreak was in Sakai, near Osaka and 6,309 cases of infected students and 92 school workers.

The transmission vehicles have changed and become numerous, therefore this bacteria still has the capacity to affect humans.
