Farmed salmon are pumped full of antibiotics

The misuse and overuse of antibiotics are fundamentally important issues that must be tackled. Thankfully, many salmon farms (including all ASC certified farms) do not use antibiotics preventatively, or to promote growth, or for any other unnecessary reason. Instead, they focus on preventative health care – keeping the fish healthy before they get sick. The results of preventative action are evident in the Norwegian salmon industry: a concerted effort to use vaccines and other preventative methods meant that by 2011 an academic paper found that just 0.03% of the produced biomass of the Norwegian industry was treated with antibiotics. And they have kept on improving since then: the industry recently announced that 2020 saw their lowest ever use of antibiotics.
