Cargill Meat Solutions has denied media reports that the company is phasing out its use of sow gestation stalls.

The Associated Press recently suggested that was the case, based on a letter Cargill sent to the Humane Society of the United States (HSUS), which has called on Cargill to follow Smithfield Foods’ lead in phasing out gestation crates.

Mark Klein, spokesman for the Wichita, KS-based company, says Cargill has been transitioning to group sow housing over the past four years, and has converted more than half of its production farms.

But Klein says the letter did not imply that gestation stalls were being phased out.
