In Sri Lanka, where poultry is the leading livestock industry and constitutes the only meat export industry, the majority of broiler chickens are mechanically processed in semi-automated plants. However, poultry is still slaughtered in wet markets that generally cater to specific groups of customers and ethnic groups. A 2017 study of 102 semi-automated poultry processing plants and 25 poultry-slaughtering wet markets found that 27.4% of the broiler neck skin samples from the semi-automated processing facilities tested positive for "Campylobacter" contamination, while 48% of broiler neck skin samples from the wet market processing facilities tested positive for "Campylobacter" contamination.
