People for the Ethical Treatment of Animals is once again acting its angst over California’s dairy promotions with a lawsuit.

On Wednesday, the animal-rights organization filed suit Sacramento Superior Court against California Department of Food and Agriculture (CDFA) Secretary Karen Ross, the CDFA, and the California Milk Advisory Board “for making false and misleading advertising claims about the treatment of cows on California dairy farms and for withholding thousands of related documents that PETA believes will expose the extent of their false claims,” a statement on the group’s Web site says.

A CMAB representative told Dairy Herd Management that the Advisory Board has not yet seen the alleged lawsuit, and is therefore, unable to comment on it at this time.

PETA has a history of suing over California dairy promotions. According to a report in the Sacramento Business Journal, first PETA sued the CMAB in 2002, but that action ended in 2005 after the courts decided that as a quasi- state agency, the board could not be sued as the lawsuit was filed.

PETA has also filed complaints with the Federal Trade Commission regarding dairy promotions in California.
