health hazard

i went to checkers at Merino Mall Ermelo yesterday to buy meat bones when cooking i suspected that they mixed it with pork but was not sure so i continued with cooking when we eating we realised indeed theres pork in the meat i went today to ask at checkers the Manager told me that they do mix them however they don't disclose on the label that they are mixed which this could have lead to some bad allergic reactions for me and my family since we dont eat pork. the response i got was there’s nothing they can do about it, its instructions they got from head office, in essence they don't care about our health as long they making money out of it they okay,my frustration is that what could have happened if we continued to eat the pork and no one was gonna be held accountable as even now the respond shows that. The ermelo merino checkers needs to be held accountable for this is a health hazard and we could die from this negligence
