Antimicrobials, particularly colistin, have been the first choice to control a certain type pf bacteria (Gram-negative) in pig production, and often used preventively. However, colistin is now considered to be a last resort antibiotic in human clinical practice. In 2015, the colistin resistance gene (mcr-1) was discovered in China. This mcr-1 gene was then reported in Southern Europe in 2016 in bacteria from farm animals (poultry and pigs). Currently, eight mcr genes have been reported (mcr-1 to 8)). In 2016, the EMA (European Medicine Agency) aimed to reduce use of colistin in animals in the European Union and a voluntary strategic plan to reduce colistin use in pigs was introduced in Spain. A total of 70% of Spanish pig production companies joined the program, representing 80% of Spanish pig production. The impact of these recommendations in the colistin resistance levels in pigs in Spain is reported in this article.
