Control and prevention of antimicrobial resistance in the pork production chain (LÄKÄ)

This study aims to investigate the occurrence of antimicrobial resistance in the pork production chain, identifying the means to control the increase and spread of such resistance. The results will be used in determining the extent to which consumers are exposed to resistant microbes by way of the pork production chain. Another objective is to identify means that could be used in reducing the risk of consumers being exposed to resistant microbe strains and to produce a popular information package on resistance, its emergence and means available to find protection from it.

Key measures The study will be carried out by sampling for resistance at ten farms. A litter of piglets that has received medication as well as two or three litters that have not been treated will be sampled. Furthermore, the same animals will be sampled immediately before they are sent for slaughter, at the slaughterhouse, and at the meat processing plants where carcasses, cut meat, and consumer bound meat products will be sampled for resistance. During the first visit to a pig farm, information will be gathered on the farms’s medication plan, the medication administered during the year preceding the visit, the farm’s biosecurity, and other preventive medical practices.

Expected effects and results The study will provide information on antimicrobial resistance in the production chain from the farm to the consumer. New information will be obtained on the occurrence of antimicrobial treatments and resistance. This study will also add to solutions which contribute to the understanding of proper medication and reduce the need for such medications by chancing practices and improving the protection against diseases, for example. Evidence-based information that will be obtained on the spectrum of antimicrobial medication and its use will help the parties involved to choose more effective risk management practices and facilitate the drafting of regulations and recommendations. Identifying critical areas in which antimicrobial resistance becomes more common and spreads will help decision-makers to direct measures to correct locations. A popular information package on antimicrobial resistance, its emergence and the means available to consumers to protect themselves from it will contribute to public health and the international competitiveness of the players forming the production chain.
