The fine is the largest ever issued under the US Animal Welfare Act, according to US prosecutors.

A company that breeds animals for medical testing has been fined a record $35m (£27m) after 4,000 beagles were rescued from its facility in Virginia in 2022.

The fine against Envigo RMS LLC for animal cruelty is the largest fine ever issued under the Animal Welfare Act, according to the US Department of Justice (DoJ).

“Envigo promoted a business culture that prioritized profit and convenience over following the law,” Christopher Kavanaugh, the US attorney for the Western District of Virginia, said in a statement.

“This callous approach led to dire consequences: the inhumane treatment of animals and the contamination of our waterway,” he said.

Envigo’s parent company, Inotiv, has agreed to pay the record eight-figure settlement. It has also agreed to not breed dogs for the next five years.
