A sharp decrease in the usage of antibiotics in Chile's salmon farming sector in 2022 underlines the seriousness with which farmers are handling the issue, industry executives say.
Last year 341.5 metric tons of antibiotics were used by salmon farmers in Chile, a more than 26 percent reduction over the previous 12 months. The percentage of antibiotics used per metric ton of salmon produced in 2022 was the lowest it has been since 2010, according to Sernapesca data.
Nearly 98 percent of antibiotics were deployed mainly at salmon growout sites -- the final stage in a salmon's rearing before being sent to market.
