As of July 1, 2012, raw beef liver was no longer available in restaurants in Japan because it's full of E. coli 0 157 and Campylobacter bacteria.
These bacteria cannot be killed unless the food is fully cooked, and that can be dangerous for consumers.
As a result, Japan has banned the serving of raw liver after a series of food poisoning cases last year in which five people died and 24 became seriously ill after consuming the dish at a major restaurant chain.
Regardless of the news, crowds of people still rushed to restaurants and ordered raw beef liver while they still could.
