"We obviously have a problem, at least according to German government data," said Urvashi Rangan, a senior scientist with Consumers Union, a nonprofit consumer advocacy group.

Salmon is one of the top seafood items on American menus. Most of it is farm-raised as part of a global industry, and Chile is a leading supplier. The $2-billion-a-year Chilean industry is in crisis over an outbreak of a virus that can kill salmon but is harmless to humans.
Earlier this month, a German consumer protection agency detected antifungal and antiparasitic chemicals that are banned in Europe and the U.S. in samples of Chilean salmon. Environmentalists are also concerned about the use of antibiotics to keep penned-in fish from getting sick.
