Butchertown Slaughterhouse Faces Complaints Over Odors, No Penalties Imposed
The Swift Pork Company slaughterhouse in Butchertown, Louisville, has been the subject of 530 complaints regarding strong odors in the first half of 2026, surpassing the total for 2025. Despite the increase in complaints, the Louisville Air Pollution Control District (APCD) has not issued any violations since 2021. The odors, attributed to live pigs and rendering processes, have been detected up to three miles away. A 2023 settlement between Swift and APCD led to changes in odor regulations, requiring emissions to cause 'substantial' nuisance to a 'considerable number' of people to qualify as violations. The plant, employing 1,200 people, remains a significant source of employment in the area.
