It took years of evidence, and shouting from the rooftops, to get Defra, Britain's truly awful agricultural ministry, to acknowledge that they had a major animal and human health problem with Hepatitis E.
It will take even more pressure to get them to do something constructive about it.
Some of the more intransigent livestock veterinarians in Britain and abroad are still arguing the toss, but most are finessing their position as fast as is consistent with their dignity.
But, when Wikipedia, taken as the ultimate oracle by so many, has it, it has to be right or, at the very least, un-ignorable.

Some selected quotes on Hepatitis E:
"In the United Kingdom the Department for Environment, Food and Rural Affairs (DEFRA) said that the number of human hepatitis E cases increased by 39% between 2011 and 2012."
"DEFRA said that there was evidence that the increase in hepatitis E in the UK was due to food-borne zoonoses, citing a study that found 10% of pork sausages on sale in the UK contained the virus. Some research suggests that food must reach a temperature of 70°C for 20 minutes to eliminate the risk of infection. An investigation by the Animal Health and Veterinary Laboratories Agency found hepatitis E in 49% of pigs in Scotland."
