“…No sample was affirmative for enrofloxacin. Similar study on poultry feed samples in Bangladesh showed the presence of antibiotic residues in 18.89% samples [33]. The results of present study indicate that in recent years, indiscriminate use of antibiotics in poultry feed has drastically increased which is a matter of concern.…”

Presence of heavy metals and antibiotics in the poultry feed even in low concentrations is considered as potentially toxic and may cause hazardous effects on animal leading to accumulate in food chain. This study was performed to assess the status of heavy metals and antibiotics residue in different poultry feed samples collected from local markets of Mymensingh and Kishoreganj sadar upazila of Bangladesh. A total of 40 poultry feed samples were analyzed to detect the concentration of three heavy metals- chromium (Cr), cadmium (Cd) and lead (Pb) using atomic absorption spectrophotometry and antibiotic residues using thin layer chromatography. A survey was also conducted among 30 feed sellers in the study areas whose knowledge regarding presence of heavy metals and antibiotics residues in poultry feed was evaluated. Survey data showed that about 80% feed sellers were literate whereas 20% were illiterate. Around 23% feed sellers had knowledge about the presence of heavy metals and 90% had about antibiotic residues in poultry feeds and its detrimental public health effects. The average Cr, Cd and Pb contents in poultry feed collected from Mymensingh sadar upazila were 0.402, 1.630 and 18.314 mgkg-1, respectively. The average content of Cr and Cd in feed collected from Kishoreganj sadar upazila were 7.884 and 0.006 mgkg-1, respectively, whereas Pb content was below the detection level in this area. The results from this study showed that Cd and Pb in Mymensingh sadar upazila, Cr in Kishoreganj sadar upazila, ciprofloxacin, doxycycline and oxytetracycline in both upazilas were present at alarming levels in most of the feed samples which could be harmful for poultry as well as human health. Therefore, it is suggested to take proper steps for monitoring and regular detection of heavy metals and antibiotic residues in poultry feeds with sources identification as we as community-based awareness among the stakeholder.

“…In this study, among 120 poultry feed samples, 19 (15.83%) were residue positive with 13 (10.83%) oxytetracycline, 3 (2.5%) doxycycline, and 3 (2.5%) ciprofloxacin ( Table-2 ). Another study uncovered that about 18.89% of poultry feed samples were enriched with antibiotic residues in Bangladesh [ 38 ]. Other researchers have also found the presence of antibiotic residues in poultry feed, including enrofloxacin (46.67%), ciprofloxacin (30.00%), and amoxicillin (23.33%) [ 27 ].…”

Background and Aim: Antibiotic residues in livestock farming have been identified as a potential cause of antimicrobial resistance in humans and animals. This study aimed to determine whether antibiotic residues were present in the chicken meat, eggs, feces, and feed collected from all four districts in the Mymensingh division of Bangladesh. Materials and Methods: To detect antibiotic residues in the collected samples, qualitative thin-layer chromatography (TLC) and quantitative high-performance liquid chromatography (HPLC) were used. A total of 230 samples were analyzed for commonly used 11 antibiotics residue. Out of these, 40 meats and 40 feces samples were collected from broilers and layers, 30 egg samples from duck and layer, and 120 feed samples from both broilers and layers from the study area. Thin-layer chromatography was used for screening the presence of antibiotic residues; TLC-positive samples were then subjected to further HPLC analysis to determine the residue concentrations. Results: Thin-layer chromatography analysis revealed that 23.5% of the tested samples contained residues from six different antibiotic classes (tetracyclines, quinolones, beta-lactams, sulfonamides, aminoglycosides, and macrolides). Thin-layer chromatography analysis showed that 35% and 25% of the meat samples were positive for residues from the broiler and layer, respectively. About 15% and 30% of layer and duck egg samples had positive residues, respectively. Out of 120 feed samples analyzed, about 15.8% had various antibiotic residues. In addition, feces samples from broilers and layers had 50% and 35% antibiotic residues, respectively. A total of 2.5% meat and 3.3% egg samples had antibiotic residues above the maximum residue limit (MRL). Based on the findings of this study, the highest percentage of oxytetracycline, followed by doxycycline and ciprofloxacin, were detected in feed samples, and oxytetracycline was detected in meat and egg samples. Conclusion: This study clearly showed the misuse of antibiotics in the poultry sector in Bangladesh. Although antibiotic residues below the MRL level are suitable for human consumption, they may result in antimicrobial drug resistance to pathogens. Keywords: antibiotic residues, broiler, high-performance liquid chromatography, layer, maximum residue limit, thin-layer chromatography.
