Special Issue Information

Dear Colleagues,

Animal-originated food products (e.g., meat, dairy, egg products) rich in protein and nutrients form the baseline of a well-balanced human diet. Nevertheless, livestock producers in primary animal production are struggling to maintain high yields of the respective food commodities (e.g., meat, milk, eggs), as bacterial diseases in animal production remain a significant challenge worldwide affecting production performance, profitability and animal welfare. In an effort to control pathogenic bacteria in primary animal food production, antimicrobials are widely used and administered in farm animals in the form of antibiotic treatment or through feed and/or water supplementation. However, it is well-known that antimicrobial misuse may confer resistance in animal and human bacterial pathogens, thus posing a significant threat for public health in the context of the One Health approach through the consumption of food. This Special Issue focuses on the detection and presence of pathogenic bacteria in the primary animal production environment, as well as on the acquired antimicrobial resistance phenotypes and/or genotypes of those pathogens. Furthermore, the occurrence of bacterial pathogens in foods of animal origin, along with their screening for antimicrobial resistance, is also of interest for this Special Issue.

Irrational use of antimicrobials in humans, livestock, and poultry is often cited as the key driver of the accelerated emergence of antimicrobial resistance (AMR) in humans and animals. In Pakistan, the use of antimicrobials in livestock and poultry is not well-regulated, owing to limited and/or ineffective implementation of existing legislations and lack of coordination amongst the key stakeholders. To gather data and information pertinent to the supply chain mapping and the usage of antibiotics in the livestock and poultry sectors of Pakistan, a national workshop for selected influential stakeholders was held in Islamabad, Pakistan during March 2020 to map the supply chain and the usage of antibiotics in the country. Participants from all relevant organizations identified the supply chain and discussed the status, challenges, and the way forward to enhance data collection and monitoring of antimicrobial usage (AMU) in livestock and poultry sectors to contain the emergence of AMR. The pre-workshop questionnaire was designed to gather relevant information on AMU and its distribution among diverse markets and users from the workshop participants, utilizing open-ended questions. A chart depicting the relative magnitude of an antimicrobial use (AMU) supply chain was constructed to illustrate the flow of antimicrobials from import and production to end-use at the farm level. This chart was shared with participants to gather their professional opinions and potential corrections. It also presented a list of agencies and their roles in regulating AMU, along with the types of AMU data available at each level. Specific recommendations were made at the end of the workshop to review and update legislation to cover the entire AMU supply chain, enhance regulations to restrict the use of antimicrobial growth promoters, build an integrated national AMU database system, and raise awareness about the responsible use of antimicrobials in the livestock and poultry sectors. It was concluded that the AMU supply chain in the veterinary sector of Pakistan is fragmented and is co-regulated by various federal and provincial stakeholders. There are some drugs, such as antibiotic growth promoters, which are not regulated at all. The approach and findings from this study can serve as a model to validate the use and management of antibiotics in other, similar countries currently grappling with serious antimicrobial resistance (AMR) crises.
