The actions and the sounds will make you cringe.
A Mercy for Animals representative says he went undercover working ten weeks at a Minnesota farm early this year and recorded the disturbing images.
The pigs are crammed into gestation crates with no room to move around or lay down for much of their lives.
"Common sense tells us that animals should, at a minimum, be given the freedom to walk, stretch their limbs, and engage in other natural behaviors," Becca Frye, Mercy for Animal's education director.
As a result of the video, Mercy for Animals said a number of food providers and grocery retailers have demanded Christensen Farms get rid of the crates.
But they say Walmart hasn't said a word.
"Walmart not only has the ethical responsibility but also the enormous purchasing power to ensure the pork sold in its stores is not a product of egregious animal abuse."
FOX16 worked the phone this afternoon. We left a message for Walmart and Christensen Farms.
On the farm's website, they address the video with this statement.
It reads in part: "The company performs periodic internal audits in addition to utilizing external expertise to provide input and perspective on production practices including animal welfare standards."
"As a civilized society, it's our moral obligation to make sure all animals are protected from needless suffering, including farmed animals," Frye said.
Statement from Walmart
“We will not tolerate animal mistreatment by our suppliers. As soon as we were made aware of the video, we immediately reached out to our suppliers who source from this farm. If we determine that there was mistreatment, we will take action.
We currently offer gestation crate-free pork products in a number of stores across the U.S.
We have been having and will continue on-going discussions with our suppliers, NGOs and food safety experts to find ways to increase that number.
We believe in offering our customers a choice.”
