"A leading British supermarket may unwittingly have infected thousands of people with a pig virus that causes liver cirrhosis and neurological damage, say researchers at Public Health England.
Hepatitis E (HEV) is transmitted by sausages and pork products from Europe, mainly Holland and Germany. UK pigs do not have the virus strain in question.
Scientists at PHE, a government agency, have traced the shopping habits of infected people and found that a common factor is consumption of own-brand sausages from “Supermarket X”.
PHE and the Food Standards Agency (FSA) have refused to name Supermarket X but two separate sources said it was Tesco."
