In addition to conventional IKB pigs (pigs bred and slaughtered according to the minimum legal standards), Westfort also slaughters pigs for the KDV (Sustainable Pork Chain), KDV+ (Antibiotic-Free Life Guarantee), EKO (organic pork), and Beter Leven (the quality mark of the Dutch Society for the Protection of Animals (Dierenbescherming)) concepts. ^[43] Regarding animal welfare during the slaughter process, the criteria for these various concepts differ little, if at all, from standard legislation. KDV, a collaboration between Westfort slaughterhouses, pig farmers, and retailers, stands out by providing additional comforts in the slaughterhouse's waiting pens, such as underfloor heating. Compliance with KDV criteria at the slaughterhouse is monitored by Westfort's own QUESH (Quality, Health, Safety, and Environment) department. ^[44] Antibiotic-free Life Guarantee or KDV+ is a premium quality mark of KDV ^[45] and adheres to the same slaughterhouse standards as KDV. KDV pork is available at supermarket chains such as COOP, MCD, and POIESZ. ^[46] Pigs for KDV pork are exclusively slaughtered at Westfort.

For "Beter Leven" pork, the Dutch Society for the Protection of Animals (Dierenbescherming) works with several slaughterhouses, including Westfort. Beter Leven pork is sold in various Dutch supermarkets such as Albert Heijn, Jumbo, Lidl, and Aldi. The Beter Leven criteria for slaughter primarily adhere to legal standards, with additional measures including a ban on the use of electric devices and a prohibition on housing animals from different transports together in a holding pen. Beter Leven certificates are not granted to slaughterhouses where, in addition to regular slaughter, unstunned (ritual) slaughter occurs (which does not apply to pig slaughterhouses). ^[47] Inspections for the Beter Leven quality mark are conducted by Certification Bodies accredited by the Dutch Accreditation Council. If no deviations are identified during the inspection, the Beter Leven certificate is issued for a duration of one year. ^[48]

The EKO quality mark signifies organic production, which is overseen by Skal Biocontrol. The regulations governing organic production do not specify criteria for the slaughter process of animals. ^[49] Meat from organic pigs slaughtered at Westfort in Ijsselstein is processed at Westfort's organic meat processing facility in Hedel (Deli Harmony). Deli Harmony sells the organic pork under the consumer brand "St. Hendrick." ^[50] which is available at supermarket chain Ekoplaza, among others. ^[51]

The undercover footage from Westfort slaughterhouse reveals a stark contrast to the animal-friendly image that quality marks aim to present. Pigs are beaten with electric prods or grabbed by sensitive areas like their ears. Being chased and faced with the unfamiliar environment of the slaughterhouse, which is far from the natural settings where pigs feel at ease, leads to significant stress and anxiety. All pigs at Westfort, as well as at other slaughterhouses, are stunned and slaughtered in the same manner, following the guidelines set out in REGULATION (EC) No. 1099/2009 on the protection of animals at the time of killing. The process of slaughtering animals for meat consumption inevitably involves animal suffering, no matter the quality mark.
