Opinions of Spanish pig producers on the role, the level and the risk to public health of antimicrobial use in pigs

Abstract

Antimicrobial use is a major driver of antimicrobial resistance and prescribers (physicians and veterinarians) and end users (patients, food producers and pet owners) are the cornerstones of this scenario. Intensive pig farming is a livestock activity that has a high antimicrobial use. This study is based on the opinions of pig producers. The study was done at national level and comprised two independent cross-sectional surveys using a questionnaire-based methodology and face-to-face interviews carried out between April and October, 2010. The collected data, which consisted of opinions of producers on 48 farrow-to-finish farms and 62 finisher farms, showed that, irrespective of farm type, pig producers in Spain have an imperfect knowledge of the main use of antimicrobials. Antimicrobials are perceived as valuable cost-effective tools for animal health and husbandry and there is little concern among pig producers about the harmful effects on public health of on-farm antimicrobial use.
