Small-Scale Food Animal Production and Antimicrobial Resistance: Mountain, Molehill, or Something in-between?
Open accessAbstract
SUMMARY: Small-scale food animal production is widely practiced around the globe, yet it is often overlooked in terms of the environmental health risks. Evidence suggests that small-scale food animal producers often employ the use of antimicrobials to improve the survival and growth of their animals, and that this practice leads to the development of antimicrobial resistance (AMR) that can potentially spread to humans. The nature of human-animal interactions in small-scale food animal production systems, generally practiced in and around the home, likely augments spillover events of AMR into the community on a scale that is currently unrecognized and deserves greater attention. https://doi.org/10.1289/EHP2116.

Sick animals in urban informal settlements are typically treated without veterinary consultation and with antibiotics purchased without a prescription from veterinary shops or from the same pharmacies that residents frequent.
“Sick animals are typically treated without veterinary consultation and with antibiotics that have been purchased without a prescription from veterinary shops, or from the same pharmacies that residents frequent for their own medical needs 41 .”
From Urban informal settlements as hotspots of antimicrobial resistance and the need to curb environmental transmission. (2020) · cites this paper as [41]
The 'Antimicrobial Use in Small-Scale Food Animals' section says antimicrobials are often available over the counter in animal-agriculture shops and that small-scale producers may lack veterinary assistance. Its examples also describe farmers treating animals themselves or buying antimicrobials at local shops. The section does not establish that this is typical in urban informal settlements or that antibiotics are bought from the same pharmacies residents use for their own medical needs. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
