There are people from France, Belgium and the Netherlands who allegedly falsified documents, misled horse owners and violated sanitary regulations between 2010 and 2015.
They are accused of lying to owners of aging horses, telling them their horses would go to the countryside but were instead slaughtered.
The charges are fraud, conspiracy to commit fraud, and misleading consumers and endangering their health.
The plaintiffs include France's veterinary association, the Alex municipality, and the cattle and meatpacking association ANBV.
