Danielle Ann of Alvinology reports researchers at the Singapore General Hospital have found definite similarities between the virus strains of Hepatitis E virus or (HEV) in pig liver and human liver.

This means that ingesting raw pork liver could mean you’re ingesting a strain of HEV that’s similar enough to human HEV that it could cause you get infected.

The same report said that people who have contracted HEV has risen steadily over the years. While the researchers could not say if the ingestion of raw pig liver is the main cause of the rise in cases, many local dishes feature this ingredient and do not cook the meat thoroughly.

The same report said that you can acquire the disease from eating contaminated food or substances. Ingesting water that is laced with the disease or accidentally drinking water that has trace amounts of faeces. Eating raw or half-cooked meat that is infected can also transmit the virus to you.
