ASUNCIÓN, Paraguay – Chile used almost 350 times more antibiotics in its farmed salmon in 2008 than Norway, its chief competitor and the largest salmon producer in the world, according to official data from both countries.

Chile’s Economy Ministry revealed this month that Chile used almost 718,000 pounds of antibiotics in 2008 and more than 850,000 pounds in 2007.

Based on information published by the Norwegian Institute of Public Health, that was about 346 times the amount of antibiotics Norway used in 2008 (2,075 pounds), and almost 600 times the amount Norway used in 2007.

Chile’s economy minister, Hugo Lavados, detailed Chile’s use of antibiotics in salmon production in response to a request for information by the environmental group Oceana under the country’s new information access law. It was the first time the government had released such figures publicly, environmental groups said.

“The ministry’s numbers confirm that the Chilean salmon industry has abused the use of antibiotics,” said Alex Munoz, Oceana’s vice president for South America. “They also show that the Chilean government has placed a higher priority on ensuring the profitability of a business sector than protecting consumers and the nation’s ecosystems.”
