(Reuters) – Meat processor Tyson Foods Inc (TSN.N) said U.S regulators have not recommended any enforcement action after they concluded a probe related to allegations the company fixed chicken prices along with its peers for years.

The No. 1 U.S. meat processor and a handful of other large meat companies have been accused of antitrust violations relating to the pricing, production of broiler chicken and compensation to farmers.

Tyson, Pilgrim’s Pride Corp and Sanderson Farms Inc received a subpoena from the U.S. Securities and Exchange Commission on Jan. 20 after U.S. poultry buyers filed a lawsuit last year.
