Campaign group GMO Free USA, which also goes by the name Toxin Free USA, has filed a false advertising lawsuit against the US division of German supermarket chain Aldi, claiming the retailer deceptively markets its Atlantic salmon products as “Simple. Sustainable. Seafood.”

Aldi, which sources some of its salmon from Chilean farms, misled consumers with the marketing, since salmon farming is "ecologically dangerous...spread[ing] feces, chemicals, parasites and disease into the surrounding environment."
