The use of antimicrobial drugs in poultry is an important public health issue owing to the increased use of such compounds that may trigger harmful effects on consumers. This study investigated the type and concentration of tetracyclines in poultry meat samples collected from Amman city, Jordan. A total of 180 samples (breast muscles, livers and kidneys) were randomly collected from the abattoir and screened qualitatively using the Premi® test and quantitatively by High-performance liquid chromatography (HPLC) for oxytetracycline, tetracycline and chlortetracycline. Approximately eighty-four (46.6%) of the samples showed a positive result for the presence of tetracycline residues. Out of the 84 positively samples, parent drugs were identified in 12 (6.6%) muscle, 14 (7.7%) liver and 13 (7.2%) kidney samples. Moreover, the samples that exceeded the maximum residue limit were 4.4%, 5.0%, and 2.7% of muscle, liver, and kidney, respectively. Freezing (-70°C for 90 days) and heat treatments (up to 90°C for 60 mins) did not significantly reduce tetracyclines residue concentrations. Violative levels of antimicrobial drug residues in different poultry tissues are still a public health issue. An extra-dosage regimen or failure to meet the withdrawal times might stand behind the problem. Private and governmental strategies to implement strict regulations on antimicrobial applications in the poultry industry are highly recommended. Poultry producers should be informed that the usage of antibiotics does not compensate for hygienic measures at farm levels.

Abstract

The use of antimicrobial drugs in poultry is an important public health issue owing to the increased use of such compounds that may trigger harmful effects on consumers. This study investigated the type and concentration of tetracyclines in poultry meat samples collected from Amman city, Jordan. A total of 180 samples (breast muscles, livers and kidneys) were randomly collected from the abattoir and screened qualitatively using the Premi® test and quantitatively by High-performance liquid chromatography (HPLC) for oxytetracycline, tetracycline and chlortetracycline. Approximately eighty-four (46.6%) of the samples showed a positive result for the presence of tetracycline residues. Out of the 84 positively samples, parent drugs were identified in 12 (6.6%) muscle, 14 (7.7%) liver and 13 (7.2%) kidney samples. Moreover, the samples that exceeded the maximum residue limit were 4.4%, 5.0%, and 2.7% of muscle, liver, and kidney, respectively. Freezing (-70°C for 90 days) and heat treatments (up to 90°C for 60 mins) did not significantly reduce tetracyclines residue concentrations. Violative levels of antimicrobial drug residues in different poultry tissues are still a public health issue. An extra-dosage regimen or failure to meet the withdrawal times might stand behind the problem. Private and governmental strategies to implement strict regulations on antimicrobial applications in the poultry industry are highly recommended. Poultry producers should be informed that the usage of antibiotics does not compensate for hygienic measures at farm levels.
