“…Acetaminophen (i.e., the active ingredient of the pain reliever Tylenol) was detected in 10 of 12 feather meal samples, and in both samples from China, where it has been used as a feed additive. 35 Acetaminophen is also administered to poultry in the European Union to treat painful diseases and fever. 36 The Table 1.…”

Antimicrobials used in poultry production have the potential to bioaccumulate in poultry feathers but available data are scarce. Following poultry slaughter, feathers are converted by rendering into feather meal and sold as fertilizer and animal feed, thereby providing a potential pathway for reentry of drugs into the human food supply. We analyzed feather meal (n = 12 samples) for 59 pharmaceuticals and personal care products (PPCPs) using EPA method 1694 employing liquid chromatography tandem mass spectrometry (LC/MS/MS). All samples tested positive and six classes of antimicrobials were detected, with a range of two to ten antimicrobials per sample. Caffeine and acetaminophen were detected in 10 of 12 samples. A number of PPCPs were determined to be heat labile during laboratory simulation of the rendering process. Growth of wild-type E. coli in MacConkey agar was inhibited by sterilized feather meal (p = 0.01) and by the antimicrobial enrofloxacin (p < 0.0001) at levels found in feather meal. Growth of a drug-resistant E. coli strain was not inhibited by sterilized feather meal or enrofloxacin. This is the first study to detect antimicrobial residues in feather meal. Initial results suggest that more studies are needed to better understand potential risks posed to consumers by drug residues in feather meal.

“…These transferable plasmids carry mobile genetic DNA elements (integrons) that often contain numerous genes for resistance to antibiotics, which are transferred simultaneously to other bacteria, where they are jointly expressed (Schroeder, Hoog, & Helmuth, ). According to Martins da Costa, Oliveira, Ramos, and Bernardo (), the phenomenon of coselection is hugely important in the persistence of multiresistant strains which are, moreover, stable and capable of lingering on farms long after any selective pressures have disappeared (Song et al, ).…”

Beef preparations (meatballs, minced meat, hamburgers, white sausages, and red sausages) from northwest Spain were tested. Microbial counts ranged from 0.70 ± 0.00 log10 cfu/g (enterococci) to 9.57 ± 0.37 log10 cfu/g (psychrotrophs). In 73.3% of cases, total aerobic counts were higher than the microbiological limits set for the end of the manufacturing process in the European Union (EU Regulation 2073/2005). Forty Escherichia coli isolates were tested against thirteen clinically important antibiotics (disk diffusion method; CLSI). Three of the strains (7.5%) were susceptible to all the antibiotics, four (10.0%) showed resistance or reduced susceptibility to one antibiotic, and 33 (82.5%) were multiresistant (with resistance or reduced susceptibility to between two and eight antibiotics), with an average of 1.85 resistances per strain. The highest rates of resistance were observed for two antimicrobials widely used on cattle farms (cefalotin and tetracycline). The findings in this research emphasize the need to correctly handle beef preparations with the aim of reducing risks to consumers.

“…Owing to its high concentration in chicken lung [4,5], danofloxacin has been widely used in China for the control of respiratory bacterial infections in chickens [6,7], bovine and swine since 1999. However, a recent investigation performed in China showed that the percentage of Escherichia coli isolates from Chinese poultry resistant to fluoroquinolones was fairly high (57.1-66.7%) [8]. This may raise public health concerns regarding reduction in the clinical efficacy of fluoroquinolones in human medicine.…”
