From NYTimes.com: Salmon Virus Indicts Chile's Fishing Methods
A virus called infectious salmon anemia, or I.S.A., is killing millions of salmon destined for export to Japan, Europe and the United States. The spreading plague has sent shivers through Chile's third-largest export industry, which has left local people embittered by laying off more than 1,000 workers.It's a real problem that consumers don't know where their food comes from or what's been used in the process of creating it.
But the latest outbreak has occurred after a rash of nonviral illnesses in recent years that the companies acknowledge have led them to use high levels of antibiotics. Researchers say the practice is widespread in the Chilean industry, which is a mix of international and Chilean producers. Some of those antibiotics, they say, are prohibited for use on animals in the United States.
Many of those salmon still end up in American grocery stores, where about 29 percent of Chilean exports are destined. While fish from China have come under special scrutiny in recent months, here in Chile regulators have yet to form a registry that even tracks the use of the drugs, researchers said.
That's why not eating fish is a good thing! :)
