Campbell took samples of the blood directly from the pipe flow and sent them to activist and researcher Alexandra Morton, who delivered them to Atlantic Veterinary College in Prince Edward Island for analysis. Morton found that the blood contained intestinal worms, as well as Piscine Reovirus, a virus that’s common in wild and farmed Atlantic salmon, and is linked to heart and skeletal muscle inflammation (HSMI) in fish. The virus isn’t known to be harmful to humans, but can kill as much as 20 percent of an infected fish population.
