Video showing cows at a Wisconsin dairy farm being stabbed, kicked and whipped prompted the pizza maker DiGiorno to stop using the farm, as the advocacy group that secretly filmed the footage pushed for harsher sanctions against the facility.

WTMJ-TV reported on Friday that four employees of Wiese Brothers Farm have been charged with 11 counts of animal cruelty in connection with the beatings shown in the October 2013 video. Another two employees have been fired and one more was reassigned to a position keeping them away from animals.

But Matt Rice, whose activist group, Mercy With Animals, filmed the beatings, pointed out to WTMJ that Wiese Brothers itself was not fined or charged.

“So far, we’ve not gotten any indication that they’ve taken steps to implement policies that would prevent this type of abuse from happening at its other facilities,” Rice told WTMJ.

ABC News reported that the Wiese Brothers facility supplied milk to DiGiorno through the use of a farming collective, Foremost Farms, for use in its frozen pizza products.

But after the footage was revealed, Nestle, DiGiorno’s parent company, informed Foremost that it would not use the Wisconsin farm’s milk anymore.

“Nestle is outraged and deeply saddened by the mistreatment of animals shown in this video,” the company said in a statement. “We expect all of our suppliers and their suppliers to meet our stringent guidelines Nestle is committed to proper animal handling We will not knowingly work with companies that violate our Responsible Sourcing Guidelines .
