A lawsuit alleges that a large smoked salmon processor in Maine does not use sustainable practices, contrary to labeling on its products.

The suit filed in U.S. District Court in Maine is brought against Ducktrap River of Maine by a consumer and New York resident, Abigail Starr, the Portland Press Herald reported on Monday.

Ducktrap River is located in Belfast and is operated by a subsidiary of Mowi ASA, a Norwegian company. Some of the salmon and other seafood products listed on its website are printed with certifications from fish farming industry groups.

The lawsuit seeks class action status and unspecified damages, which could increase if a court found that the company misled consumers and acted willfully. The lawsuit argues that industrial fish farming endangers public health, causes animal suffering and environmental damages. It also alleges that the company violated consumer protections, the newspaper reported.

The company’s general manager Don Cynewski told the newspaper he was aware of the lawsuit and had no comment.
