( CNN ) -- Five workers at an Idaho dairy have been fired after an undercover video by animal rights activists showed mistreatment towards cows , the dairy owner said . Three of the workers have been charged with misdemeanor cruelty to animals , according to Twin Falls County District Court records . Luis Bettencourt , owner of Bettencourt Dairies , told CNN his family-owned operation of 30 years was `` appalled '' at the video -- which the Mercy for Animals group says depicts workers and supervisors `` violently hitting , stomping on , punching and kicking cows in the face and body . '' The Idaho Department of Agriculture informed the dairy of the tape about five weeks ago , and Bettencourt fired all the individuals filmed in the mistreatment , he said . Since then , the business has installed video cameras to watch employees , he added . Opinion : Farmers are n't evil . Now can we have a civil conversation ? `` We are all devastated by it . We are family owned and we love our cattle , '' Bettencourt told CNN . `` It 's something we do n't allow , and it 's been a hard five weeks . '' Bettencourt Dairies , based in Wendell , Idaho , has 13 milking facilities with about 60,000 cows and about 500 employees , its website says . The video was taken at the firm 's Dry Creek Dairy site outside Hansen , Idaho , where about 10,000 Holstein cows are kept , the animal rights group said . All 500 employees at 11 dairies have seen the video , and each has signed a document about zero tolerance on animal abuse , Bettencourt said . The workers who have been charged are Jesus Garza , 24 ; Jose Acensio , 28 ; and Javier Victor Rojas Loayza , 39 .

Kraft Foods said the dairy provides milks to a supplier , which processes raw material for Kraft , spokeswoman Angela Wiggins said in a statement . `` While Kraft does not raise dairy cows or have milking operations , we want animals to receive proper care and be treated with respect . We have long believed high-quality dairy products begin with quality animal care , '' Wiggins said . `` Kraft condemns the handling behaviors shown in this video as they are both upsetting and unacceptable , '' she said . Burger King Corporation said the Bettencourt Dairies `` may be an indirect supplier of a small percentage of cheese products '' used in the chain 's U.S. restaurants , spokesman Bryson W. Thornton said in a statement . `` Burger King Worldwide does not have a direct relationship with Bettencourt Dairies , '' Thornton said . `` Burger King Worldwide estimates that a fraction of our dairy products , less than 1 % , could have originated at the Bettencourt facility where the video that depicts inhumane treatment of dairy cows was allegedly filmed . '' The firm `` does not tolerate or condone cruelty to animals , '' he said . Jane Velez-Mitchell : USDA needs to clean up its act . CNN 's AnneClaire Stapleton contributed to this report .
