In 2018, the Danish Veterinary and Food Administration carried out a study on the situation regarding methicillin-resistant Staphylococcus aureus (MRSA) on conventional, outdoor and organic pig farms, dairy livestock, turkeys, laying hens, mink and horses.
In the case of conventional pig farms, the study was performed on 130 farms, and 116 of them were positive for MRSA, this entailing 89% of the farms, this value being similar to a study carried out in 2015. Regarding outdoor and organic farms, of the 104 farms tested, 21 were positive (20%).
