Antibiotic use deserves serious talks, not scare tactics

    The recent release of the Food and Drug Administration’s report on antibiotic sales brought a round of calls from certain advocacy groups to ban the use of antibiotics in animal agriculture. These advocates remind me of another crowd: the anti-vaccination movement. Both the groups pushing for an antibiotic-free animal agriculture and the “anti-vaxxers” ignore established science on their respective issues in a way that leads to diminished human and animal welfare.
    We certainly should have a debate about the judicious use of antibiotics in agriculture, but jumping to an outright ban defies science and common sense, will cause more animal suffering, and may have adverse effects on public health.
    While those pushing for an outright ban are on the fringe, concerns about antibiotic-resistant bacteria in agriculture are starting to hit the mainstream. In American Humane Association’s 2014 Humane Heartland Farm Animal Welfare Survey, more than half of the respondents indicated that they seek out food labeled “antibiotic free,” second only behind “humanely raised.”

    Lack of evidence that animal antibiotic use is bad for human health

    Opponents of antibiotics frequently point to Centers for Disease Control and Prevention (CDC) estimates that at least two million Americans become infected with bacteria that are resistant to antibiotics every year. Reports indicate that the most resistant infections reside in human hospital settings. However, there is no evidence that antibiotics used in animal agriculture have decreased the effectiveness of antibiotics in humans. According to Dr. Stephanie Doores of Pennsylvania State University, “People would be more likely to die from a bee sting than for their antibiotic treatment to fail because of macrolide-resistant bacteria in meat or poultry.”
    A look across the world to Denmark is also instructive. Despite a complete ban on antibiotic use for growth promotion instituted in 2000, there is very little evidence that it led to any positive impacts on human health or a decline in antibiotic resistant bacteria. In fact, it has resulted in a significant increase in the therapeutic use of antibiotics in animals, due to animals getting sick.

    Antibiotics can and do  help animal well-being

    Science – and common sense – tell us that antibiotics can and do help improve well-being, decrease mortality rates of farm animals, and prevent unnecessary suffering. Just as they do when given to a child with strep throat, antibiotics relieve the pain and distress of sick animals while helping them to recover. One of the Five Freedoms upon which the American Humane Certified program is based is the freedom “from pain, injury and disease.” An outright ban would be inhumane to sick animals, and would violate one of the Five Freedoms that serves as the internationally accepted social contract with animals.
    Additionally, what is not often discussed is that use of antibiotics in farm animals provides for a safer food supply, and that the FDA has long required withdrawal periods for such use. As noted by Dr. Christine Hoang, assistant director of the American Veterinary Medical Association, in her 2010 testimony to the House Committee on Energy and Commerce, Subcommittee on Health: “For food animals, drugs additionally contribute to the public health by mitigating disease and thereby reducing the numbers of bacteria entering the food supply. Studies show that a reduction in the incidence of food animal illness will reduce bacterial contamination on meat, thereby reducing the risk of human illness.”

    Science-based dialogues on antibiotics needed

    Because it is an issue of concern for the public, antibiotic use in agriculture demands a healthy and robust discussion. But veterinarians, public health professionals and scientists should be determining what the appropriate use of antibiotics is. And such a discussion needs to include outcomes for the sick animal, as it’s simply not humane to leave an animal to suffer needlessly.
    Recent moves by Chick-fil-A and McDonald’s demonstrate that the issue is becoming more urgent. Let’s set aside the scare tactics and pressure campaigns and have a real, honest conversation about safe and proper antibiotic use that’s driven by science.
    Agriculture, researchers and humane organizations must work together to educate the public and food companies about proper antibiotic use, or else the dialogue will be led by misinformation. In working together, we can develop policies that improve animal health and welfare, safeguard our abundant food supply and protect public health. Better science is needed to advance a better understanding of human and animal health, and define what it is to be humane.

Animal antibiotic study launched by Colorado State University

    Colorado State University researchers are conducting studies to track antibiotic-resistant bacteria.
    From WATTAgNet:
    Colorado State University researchers are conducting a series of studies to track antibiotic-resistant bacteria in the animal agriculture industry in an effort to determine if farm practices are contributing to problems on antibiotic resistance.
    Using a $2.25 million grant from the USDA, the scientists will focus on the DNA of these bacteria to help identify and trace back where such organisms become drug-resistant. The seven research projects will focus mostly on beef and dairy operations, though some of the research will be conducted on hog and poultry farms. The projects are expected to begin in the coming weeks, Morley said.
    "We're trying to answer the question, 'Are agricultural production systems truly affecting human health by increasing antimicrobial resistance?'" said veterinarian Paul Morley, a professor of epidemiology and infection control at Colorado State University, Fort Collins.
    Using DNA sequencing technology, Morley and Keith Belk, professor in the school's Center for Meat Safety and Quality, and others plan to trace the specific genes that cause resistance in bacteria. That, they hope, will help them uncover sources and ways such "superbugs" travel between animals and humans, said Morley, one of the lead researchers in the project.
    Partners on the three-year project include the CSU departments of Computer Science; Environmental and Radiological Health Sciences; Education; and Food Science and Human Nutrition. Others include the Colorado School of Public Health, University of Colorado Health Sciences Center, Public Health Agency of Canada, USDA's Animal and Plant Health Inspection Service (APHIS), and industry collaborators providing access to their animals.

Antibiotic resistance confusion revealed in survey

    A recent survey reveals that consumers are confused about the causes of antibiotic resistance and the use of antibiotics in livestock and poultry production. The survey was conducted online in March among more than 2,100 U.S. adults by Harris Poll for the American Meat Institute (AMI).
    When asked what the greatest contributing factor to human antibiotic resistance was, only 41 percent correctly answered “health professionals over-prescribing to people.” Eighteen percent thought use of antibiotics in livestock production was the number one contributing factor according to the Centers for Disease Control and Prevention (CDC). Seven percent thought the CDC found antimicrobial hand sanitizers to be the biggest factor; five percent thought the answer was drinking water and 28 percent said they were unsure.
    During a September 2013 press conference to release a report on antibiotics, CDC Director Thomas Frieden, MD, said, “Right now, the most acute problem is in hospitals. And the most resistant organisms in hospitals are emerging in those settings because of poor antimicrobial stewardship among humans.”  In fact, he said that half of all antibiotic prescriptions given to humans are unnecessary.
    CDC also said that it is important to use good stewardship in administering antibiotics during livestock and poultry production and that animal antibiotic use for growth promotion should be phased out, an effort that is already under way at the request of the Food and Drug Administration and a move that the American Meat Institute supports.
    The survey also reflected confusion around the issue of antibiotic residues. Thirty-nine percent think that unsafe levels of antibiotics are commonly present in the meat and poultry products found at the grocery store, though government data show that violative antibiotic residues in meat and poultry are virtually non-existent.  In 2011, USDA’s Food Safety and Inspection Service screened meat and poultry for 128 chemicals, and 99 percent of the tested carcasses were free of all of them.
    To help counter the confusion, AMI has released a new, referenced and reviewed brochure called “Antibiotics in Livestock & Poultry Production: Sort Fact from Fiction.”  The brochure may be downloaded from the AMI website.  AMI also released a new “Media MythCrusher” to help the media avoid some of the most common errors in reporting about the antibiotic issue.

Perdue leader: Antibiotic use perceptions must be respected

    Consumer feelings about antibiotic use in meat and poultry production may not always be fact-based or accurate, but those feelings must still be respected by meat and poultry producers, Joe Forsthoffer, director of corporate communications, Perdue Farms, said. Speaking May 8 at the Animal Agriculture Alliance Stakeholder Summit, Forsthoffer said consumer opinions, including those regarding antibiotics, are a large driving factor in the food industry.
    “If we don’t respect the feelings of consumers and other stakeholders, they’re not going to respect us. What we’re finding is we can’t speak to them as if we’re arguing policy issues. Even if their feelings aren’t rational, they’re still valid as feelings,” said Forsthoffer.
    The summit largely revolved around the millennial generation and its views on food production, including animal antibiotic use. Forsthoffer, admittedly not a millennial, recalled that during his youth he had a special fondness for Tang and for TV dinners. While those food products were not the most wholesome or nutritious, they still held a special place in his heart. Many consumers have a similar attachment to chicken raised without antibiotics.
    In response to the demand for chicken raised without antibiotics, Perdue produces antibiotic-free brands Harvestland and Coleman Natural.
    “It is an opportunity to build stakeholder trust in the way that we operate our business, and it’s an opportunity, equally importantly or more importantly, to increase consumer confidence in our products and build a higher level of trust,” Forsthoffer said.

Antimicrobial use, resistance symposium white paper released

    The science behind the emergence, amplification, persistence and transfer of antibiotic resistance is highly complex and open to interpretation - and sometimes misinterpretation - from a wide variety of perspectives and misuse. If one thinks they understand antimicrobial resistance, it might not have been properly explained.
    The extremely complex relationship between animal health, human health and environmental health is driven by two premises. The first is that antimicrobial resistance is a naturally occurring phenomenon that is present with or without the use of antimicrobials. The second is that anytime an antibiotic enters the ecosystem, it has the potential to contribute to the development of antibiotic resistance.
    These two points were among the many shared during the "Bridging the Gap between Animal Health and Human Health" symposium sponsored by the National Institute for Animal Agriculture and conducted November 12-14, 2013, in Kansas City, Mo. These points and additional information synthesized from the symposium comprise a 27-page "Bridging the Gap between Animal Health and Human Health" symposium white paper recently released by NIAA.
    "This white paper highlights information delivered during the symposium by 20 different speakers-including antibiotic use and resistance experts representing animal health, human health and public health as well as a consumer advocate organization, grocery retailers, staff members and selected media representing agriculture and consumer advocates," states Dr. Nevil Speer, Ph.D., Western Kentucky University, and co-chair of the "Bridging the Gap between Animal Health and Human Health" symposium.
    "Open and candid presentations and discussions emphasized that those in human health and in animal health are committed to continuous improvement and are working to find common ground so a collective path forward can be formulated. Having a tug-of-war of human versus agricultural use of antibiotics doesn't advance a solution. This paper underscores the importance of taking a 360-degree view and addressing antibiotic resistance from an all-inclusive, science-based perspective."
    The Antimicrobial Use and Resistance White Paper is available on the NIAA's website. Many of the symposium's PowerPoint presentations, including the audio, are also available in full.

Antibiotic resistance is complex, open to misinterpretation

    The sharing of science-based antibiotic use and resistance information continued among experts and leaders from the animal, human and public health communities during the "Bridging the Gap Between Animal Health and Human Health" symposium sponsored by the National Institute for Animal Agriculture and conducted Nov. 12-14, in Kansas City, Mo. Adding to the symposium's insightful, transparent discussions were presentations by media and consumer advocacy group representatives as well as questions generated by symposium attendees.
    "Antibiotic resistance has been called the single most complex problem in public health, and this symposium provided respective health communities and disciplines a platform where they shared their latest research findings," states Dr. Nevil Speer, co-chair of the symposium and a professor at Western Kentucky University.
    "This year's antibiotic use and resistance symposium not only shed additional light on this often polarized topic but we identified common ground so a collective path forward that serves the best interests of all parties can be forged."
    The 170-plus symposium participants from across animal, human and environmental health heard a wealth of information, including the following 11 points:

    • The science behind the emergence, amplification, persistence and transfer of antibiotic resistance is highly complex and open to misinterpretation and misuse. If you think you understand antimicrobial resistance, it hasn't been explained properly.
    • The extremely complex relationship between animal health, human health and environmental health is driven by two premises: 1) Antimicrobial resistance is a naturally occurring phenomenon that is present with or without the use of antimicrobials; and 2) Anytime an antibiotic enters the ecosystem, it contributes to the presence of antibiotic resistance.
    • Antibiotic resistance is not just transferred from animals to humans; resistance is also transferred from humans to animals.
    • Antibiotic resistance is not just a U.S. challenge; it's an international issue that requires a strategic global One Health approach.
    • Evaluating antimicrobial resistance involves balancing risks vs. needs while constantly recognizing the importance of maintaining an efficacious arsenal of human antibiotics.
    • New tools that address food animal infectious diseases must be developed, whether they are in the field of prevention or new molecules for therapeutics.
    • Research studies and findings are often viewed through different lenses. Individuals can look at the same study and obtain different interpretation of the results and what the study infers based on their own biases.
    • Decisions should be based on science, and policy should be based on science.  The question, however, is who decides what constitutes evidence that is considered when making those decisions and policies.
    • Significant efforts are being led by the public health community to reduce inappropriate antibiotic prescribing in human health and reduce hospital-acquired infections. Agriculture needs to be open to change as well.
    • Change will happen. Open dialogue must continue, with animal agriculture at the table or change will be drastic and by statute and will not be a deliberative policy change.

Antibiotic resistance in agricultural environments

    Jean McLain, PhD, will present "Antibiotic Resistance in Agricultural Environments: A Call to Action," on Tuesday, Nov. 5, 2013 at 4:30 PM. The presentation is part of the American Society of Agronomy, Crop Science Society of America, and the Soil Science Society of America Annual Meetings, Nov. 3-7 in Tampa, Florida. The theme of this year's conference is "Water, Food, Energy, & Innovation for a Sustainable World". Members of the media receive complimentary registration to the joint meetings.
    Antibiotic resistant pathogens are an emerging, critical human health issue. The World Health Organization (WHO) has declared antibiotic resistance as a top health issue worldwide. Two million Americans are infected each year with diseases resistant to known antibiotics; between ten and fifteen thousand die.
    Most people equate antibiotic resistance to the medical field. However, antibiotic resistance is also in our soils. And, the field of agriculture has been blamed for making this worse by using concentrated feed operations that leak antibiotics into surrounding waterways. In addition, municipal water treatment systems are unable to filter antibiotics, and are being studied for their impact on the development of resistance in the environment.
    However, research shows that antibiotic resistance is a natural occurrence in our soils. Simplistically, bacteria and fungi living in soils have to compete for few food resources. Over millennia, some bacteria and fungi developed the ability to produce antibiotic chemicals in order to kill their competition. Because they produce these antibiotics, they are naturally immune to the effects of their own excretions.
    Jean McLain's study in Arizona examined resistance levels to 16 antibiotics in bacteria isolated from riparian soils in a wetland that had been recharged with wastewater for over 30 years. Resistance was very high in isolated bacteria. But, when resistance levels were compared to bacteria isolated from sediments of a nearby pond with no exposure to wastewater, resistance was equally high for 7 of the antibiotics studied. Furthermore, resistance to 5 of the antibiotics found in low levels in the wastewater-treated soils was significantly higher in the soils exposed only to groundwater. This illustrates the need for considering natural, background resistance in soils in any scientific study examining the effects of antibiotics on the environment.
    There currently is no set standard on measuring natural antibiotic resistance in soils. Knowing this baseline of antibiotic resistance is necessary for a complete picture of the problem. McLain and her colleagues have written a grant calling for worldwide experts in the field to meet and develop such standards. In her talk at the Annual Meetings, Dr. McLain will describe the various methods that could be used to measure natural background antibiotic resistance in soils and will deliver a "call to action" for all scientists currently studying antibiotic resistance.
