A consumer group is suing one the largest pork producers over allegations that the company falsely advertises its products as the “safest” in the U.S.

The Organic Consumers Association (OCA) filed a civil suit May 20 against Smithfield Foods, Inc., claiming they use practices that contribute to the creation of widespread diseases. The group is seeking to stop its ‘false’ advertising and marketing. 

Some of the practices include crowded conditions in their plants, the use of potentially carcinogenic drugs and rapid slaughter methods, according to a recent press release. These practices can lead to diseases that can be transmitted from animals to humans, OCA explained in the release.

In a May 26 statement, Smithfield denied those allegations.

“The Organic Consumers Association’s complaint against Smithfield Foods is totally without merit and the company intends to vigorously defend this lawsuit,” wrote Lisa Martin, director of corporate communications.

Smithfield Foods, Inc. is based out of Smithfield, Virginia, and is the world’s largest pork producer. Some of their brand names include Eckrich, Nathan’s Famous and Farmland.
