“…As a consequence, there is a tendency to argue against flock treatment of farm animals. A large proportion of the reduction in the amount of antimicrobials used to treat farm animals in the Netherlands has been reported to be due to the restricted use of flock treatment (33), and legal restrictions specifying certain preconditions on the use of flock medication have been gradually introduced in Denmark. Although the phasing out of oral flock treatment leads to less antibiotic usage, it has never been thoroughly investigated whether this also leads to less resistance under field conditions, where untreated animals are housed in close proximity to treated animals, and we tried to answer this question in the current study.…”

This study describes the results of a randomized clinical trial investigating the effect of oxytetracycline treatment dose and mode of administration on the selection of antibiotic-resistant coliform bacteria in fecal samples from nursery pigs. Nursery pigs (pigs of 4 to 7 weeks of age) in five pig herds were treated with oxytetracycline for Lawsonia intracellularis-induced diarrhea. Each group was randomly allocated to one of five treatment groups: oral flock treatment with a (i) high (20 mg/kg of body weight), (ii) medium (10 mg/kg), or (iii) low (5 mg/kg) dose, (iv) oral pen-wise (small-group) treatment (10 mg/kg), and (v) individual intramuscular injection treatment (10 mg/kg). All groups were treated once a day for 5 days. In all groups, treatment caused a rise in the numbers and proportions of tetracyclineresistant coliform bacteria right after treatment, followed by a significant drop by the time that the pigs left the nursery unit. The counts and proportions of tetracyclineresistant coliforms did not vary significantly between treatment groups, except immediately after treatment, when the highest treatment dose resulted in the highest number of resistant coliforms. A control group treated with tiamulin did not show significant changes in the numbers or proportions of tetracycline-resistant coliforms. Selection for tetracycline-resistant coliforms was significantly correlated to selection for ampicillin-and sulfonamide-resistant strains but not to selection for cefotaximeresistant strains. In conclusion, the difference in the dose of oxytetracycline and the way in which the drug was applied did not cause significantly different levels of selection of tetracycline-resistant coliform bacteria under the conditions tested.IMPORTANCE Antimicrobial resistance is a global threat to human health. Treatment of livestock with antimicrobials has a direct impact on this problem, and there is a need to improve the ways that we use antimicrobials in livestock production. We hypothesized that antibiotic resistance development following treatment of diarrhea in nursery pigs could be reduced either by lowering the dose of oxytetracycline or by replacing the commonly used practice of flock treatment with individual or smallgroup treatments, since this would reduce the number of pigs treated. However, the study showed no significant difference between treatment groups with respect to the number or proportion of tetracycline-resistant coliforms selected. The most important conclusion is that under practical field conditions, there will be no added value, in terms of lowering resistance development, by exchanging flock treatment for individual or small-group treatment of nursery pigs. The reason for the lack of an

“…Complementary mandatory measures were implemented, including the use of susceptibility testing before any prescription of CIA for curative purposes. To avoid competition among veterinary practices and therefore potential pressure in antimicrobial prescription and to promote farmer-veterinary relationships and farmer’s education, Dutch farmers were asked by the government to choose only one veterinary practice to provide oversight and prescription in their herds (Speksnijder et al, 2015b). In France, a “Plan Ecoantibio” program was initiated in 2012 and lasts until 2017.…”

Addressing Antimicrobial Resistance: An Overview of Priority Actions to Prevent Suboptimal Antimicrobial Use in Food-Animal Production

The growing concern regarding emergence of bacteria resistant to antimicrobials and their potential for transmission to humans via animal production has led various authorities worldwide to implement measures to decrease antimicrobial use (AMU) in livestock production. These measures are influenced by those implemented in human medicine, and emphasize the importance of antimicrobial stewardship, surveillance, infection prevention and control and research. In food producing animals, unlike human medicine, antimicrobials are used to control diseases which cause economic losses. This major difference may explain the failure of the public policies implemented to control antimicrobial usage. Here we first review the specific factors influencing AMU across the farm animal sector and highlighting the farmers’ decision-making process of AMU. We then discuss the efficiency of existing regulations implemented by policy makers, and assess the need for alternative strategies, such as substitution between antimicrobials and other measures for infectious disease control. We also discuss the interests of regulating antimicrobial prices. Finally, we emphasize the value of optimizing antimicrobial regimens, and developing veterinary precision medicine to achieve clinical efficacy in animals while limiting negative impacts on public health. The fight against antimicrobial resistance requires both a reduction and an optimization of antimicrobial consumption. The set of actions currently implemented by policy makers does not adequately address the economic interests of farmers’ use of antimicrobials.

“…First, given the public concern, European governments concluded that animal care in situations of infectious diseases can no longer be left to the discretion of the individual farmer only (Cf. Speksnijder et al 2015;Levy 2014). As a result, policies and regulations have been drafted.…”

More Than Just a Vet? Professional Integrity as an Answer to the Ethical Challenges Facing Veterinarians in Animal Food Production

Food ethics

Veterinary ethics in the context of food production is a special case that is in need of additional reflection from philosophy and veterinary professionals. To substantiate this claim two developments will be presented and analyzed in order to show the current challenges facing veterinarians specialized in farm animal health. First, I argue that in the context of farm animal health and welfare the plurality of views on the moral standing of animals evokes special difficulties. A second development focuses on the changing expectations with regard to the veterinary profession and the related extending range of competences a veterinarian needs in order to work in the agri-food sector. Next, I sketch three scenarios, often meant to deal with these developments in practice, and show that they deny the moral pluralism and the genuinely moral character of the professional responsibility of a veterinarian. Finally, I claim that professional codes or standards are important, but are insufficient to deal with these developments. I end with some remarks on the importance of professional integrity. I argue that veterinarians working in the agri-food sector need to maintain an independence from the concerns and interests of stakeholders to effectively deal with ethical challenges.
