Synopsis (short abstract) There is a pressing need to establish surveillance systems for antimicrobial use (AMU) intended for animal production, particularly in many low- and middle-income countries. This is an extremely challenging task, notably due to the wide range of animal species, production types, and antimicrobials available in the market. In Vietnam, farmers commonly buy antimicrobials from veterinary drug shops. Therefore, veterinary drug shops are a potential target for the data collection on AMU. We collected antimicrobial sales data at veterinary drug shops and estimated the amount of AMU in different animal species by antimicrobial active ingredient (AAI) class using different measurement metrics. We compiled information on all antimicrobials licensed in Vietnam and used this information to develop a mobile application to capture sales of antimicrobials intended for use in poultry, pig, and ruminant. We provided tablets with this application to 60 veterinary drug shops in two provinces of the country (Bac Giang in the north, Dong Thap in the south; three districts and 30 shops per province) for data collection over 3 weeks. Total sales of antimicrobials were extrapolated to 1 year, and these amounts were related to three different denominator estimates in each province including standing animal body weight, animal biomass, and Population Correction Unit (PCU). A total of 3,960 transactions [2,577 (median 75.5 per shop) in Bac Giang; 1,383 (median 28.5 per shop) in Dong Thap] of 831 different antimicrobial-containing products were recorded in the 3-week period. Sales of 57 AAIs belonging to 17 classes were recorded. In the three Bac Giang districts, we estimated that 242.0 kg of AAI were hypothetically sold over 1 year. Of those, 202.2 kg (83.6%) were intended for poultry, 19.8 kg (8.1%) for pigs, and 20.0 kg (8.3%) for ruminants. In Dong Thap, an estimated 48.4 kg of antimicrobials were sold, including 28.9 kg (59.7%) for poultry, 16.0 kg (33.1%) for pigs, and 3.5 kg (7.2%) for ruminants. After standardized by different animal population denominators, AMU in Bac Giang amounted to 1129.2 mg/kg standing animal body weight, 480.2 mg/kg biomass, and 636.1 mg/kg PCU. In Dong Thap, AMU figures were 1211.0 mg/kg standing animal body weight, 595.8 mg/kg biomass, and 818.5 mg/kg PCU. We discuss the observed differences between species, location and metrics, as well as the potential advantages and limitations (including potential sources of bias) of this methodology and its applicability at the country level. Retail level data collection can effectively be integrated

    Joint FAO/OIE/WHO Expert Workshop on Non-Human Antimicrobial Usage and Antimicrobial Resistance: Scientific assessment
    Geneva, December 1 – 5, 2003

    Antimicrobial agents are essential drugs for human and animal health and welfare. Antimicrobial resistance is a global public health concern that is impacted by both human and non-human antimicrobial usage. Antimicrobial agents are used in food animals, including from aquaculture, companion animals and horticulture to treat or prevent disease. Antimicrobial agents are sometimes used in food animals to promote growth. The types of antimicrobials used are frequently the same as, or closely rela ted to, antimicrobials used in humans.

    The expert workshop concluded that there is clear evidence of adverse human health consequences due to resistant organisms resulting from non-human usage of antimicrobials. These consequences include infections that would not have otherwise occurred, increased frequency of treatment failures (in some cases death) and increased severity of infections, as documented for instance by fluoroquinolone resistant human Salmonella infections. Evidence shows th at the amount and pattern of non-human usage of antimicrobials impact on the occurrence of resistant bacteria in animals and on food commodities and thereby human exposure to these resistant bacteria. The foodborne route is the major transmission pathway for resistant bacteria and resistance genes from food animals to humans, but other routes of transmission exist. There is much less data available on the public health impact of antimicrobial usage in aquaculture, horticulture and companion an imals.

    Carryover in feed and transfer from feed to food of unavoidable and unintended residues of approved veterinary drugs
    Report of the Joint FAO/WHO expert meeting – 8–10 January 2019, FAO Headquarters, Rome, Italy

    Carryover of veterinary drugs in feed can occur during feed processing, handling, transportation, delivery or in feeding animals on-farm. The risk of unavoidable and unintentional veterinary drug residues from feed carryover and/or transfer from feed to food of animal origin is unacceptable when it causes adverse health effects in target and/or non-target animals and/or humans consuming food originating from these animals. If carryover is not properly managed, contaminated feed can directly harm species that are sensitive to the unintended veterinary drug they consume, and /or can result in residues in food of animal origin such as meat, milk and eggs that render them unsafe for human consumption. Even if residues are not a safety hazard, they can pose regulatory and global trade issue as countries/markets may enforce a “zero” tolerance for residues when appropriate maximum residue limits have not been established. Upon request of the Codex Committee on Residues of Veterinary Drugs in Foods (CCRVDF), FAO and WHO convened an Expert Meeting to review the causes of veterinary drug carryover in animal feed and the transfer from feed to food, as well as the known risks to human health and international trade, and suggest appropriate risk management strategies. This report shows the results of the expert discussions, conclusions and recommendations.

    Knowledge, attitudes and practices of livestock and aquaculture producers regarding antimicrobial use and resistance in Vietnam 2019
    Also available in:
    No results found.
    The use of antibiotics in livestock production is considered a major driver of antibiotic resistance on a global scale. In Vietnam, small- and medium-scale livestock producers dominate the domestic market and regulatory pushes have done little to decrease antibiotic use. In order to inform future policy directions, this study aims to explore knowledge, attitudes, and practices amongst livestock producers to identify their perspectives on antibiotic use and resistance.
