Varkens in Nood has identified regular mistakes in the stunning and killing of pigs in slaughterhouses, as shown by NVWA reports. These errors are not consistently corrected, leading to pigs being conscious during slaughter and improperly killed pigs. The organization is calling for a 'zero tolerance policy' for violations and the implementation of a mandatory check to ensure pigs are stunned before slaughter, followed by a check to confirm death before the scalding tank. Stricter penalties for slaughterhouses with errors are also demanded.
