Letter regarding “Gastrointestinal foreign bodies in pet pigs: 17 cases”
Bibliographic record
Abstract
We note the article, “Gastrointestinal foreign bodies in pet pigs: 17 cases” by Nakamae et al and applaud the authors for this contribution to the growing literature of miniature companion pig medicine. However, we have noticed an inconsistency in the language of the article, and discussion of such could serve to educate the community of veterinarians treating miniature companion pigs in North America. The article states, “Authors declare no off-label use of antimicrobials.” However, the authors report that the pigs in the study received multiple antimicrobials including “… cephalosporins (n = 8), beta-lactams (n = 8), tetracyclines (n = 1), macrolides (n = 1), and aminoglycosides (n = 1).” The “no off-label use” statement contradicts the reported administration of antimicrobial drugs, as none of these drugs are labeled for surgical prophylaxis or similar indications in the United States. Ceftiofur is labeled for the treatment of swine respiratory disease. While the specific beta-lactams, tetracyclines, macrolides, and aminoglycosides administered are not specified in this report, the swine labelling of these drugs does not include surgical prophylaxis. Procaine penicillin G (beta-lactam) is approved for pigs for treatment of erysipelas, oxytetracycline (tetracycline) is approved for treatment of bacterial pneumonia, tulathromycin (macrolide) is approved for the treatment of swine respiratory disease, and a formulation of gentamicin (aminoglycoside) exists for treatment of colibacillosis caused by E. coli in pigs up to 3 days of age. The article does not state if any of the pigs had concurrent conditions, specifically those the drugs are labeled for. Under the 2012 FDA Order of Prohibition regarding the use of cephalosporin drugs in major food-producing animals (including swine as defined by 21 CFR 516.31), the first specifically stated prohibition is for disease prevention purposes,2 and it should be noted that surgical prophylaxis could be classified as such. All the aforementioned antimicrobial drugs can be used legally in an extra label manner in food animal species in the United States and Canada under a valid veterinary-client-patient relationship. This is an important distinction, as food animal status is determined by species, not role. While not common, there are documented cases of companion miniature pigs entering the human food chain.3 While this is an unlikely event, practitioners should receive and notify clients of withdrawal recommendations by contacting the Food Animal Residue Avoidance Databank (FARAD; US) or the Canadian global Food Animal Residue Avoidance Databank (CgFARAD) any time drugs are prescribed or administered to swine, regardless of the intended use of the animal. We sincerely thank the authors' contribution to the growing body of literature about miniature pigs. In submitting this letter, we wish to emphasize the importance of adhering to extra label drug use requirements with respect to the current environment of antimicrobial stewardship, especially in relation to the potential dual consideration of miniature companion pigs as pet and food animals. Respectfully,

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
