Antibiotic residues in muscle tissue of chickens sold in markets in the city of Ayacucho, Peru

Chicken meat is one of the primary sources of animal protein in Peru. However, the intensive use of antibiotics in poultry production can result in pharmacological residues in muscle tissues, posing risks to food safety and public health. This study aimed to detect antibiotic residues in chicken mea...

However, the intensive use of antibiotics in poultry production can result in pharmacological residues in muscle tissues, posing risks to food safety and public health. This study aimed to detect antibiotic residues in chicken meat sold in markets in the city of Ayacucho, Peru, during 2025. A total of 70 samples were collected from three local markets and analyzed using the microbiological agar diffusion method with Bacillus subtilis ATCC 6633 and Micrococcus luteus ATCC 9341 as indicator organisms. Antibiotic residues were detected in 18.6% of the samples, with sulfamethoxazole (38.5%) and erythromycin (30.8%) being the most frequently identified compounds, followed by penicillin and streptomycin (15.4% each). These findings indicate a potential risk to consumers. The frequent detection of sulfamethoxazole and erythromycin residues in chicken meat highlights the need for strengthened health surveillance and effective regulatory controls to reduce the risk of antimicrobial resistance and ensure food safety at both national and global levels.   El consumo de carne de pollo representa una de las principales fuentes de proteína animal en el Perú. Sin embargo, el uso intensivo de antibióticos en la producción avícola genera residuos farmacológicos en los tejidos musculares, que representa un riesgo para la inocuidad alimentaria y la salud pública. El presente estudio tuvo como objetivo detectar residuos de antibióticos en carne de pollo comercializada en los mercados de Ayacucho durante el año 2025. Se recolectaron 70 muestras provenientes de tres mercados locales, las cuales fueron analizadas utilizando el método microbiológico de difusión en placa con Bacillus subtilis ATCC 6633 y Micrococcus luteus ATCC 9341. Los resultados indicaron que el 18,6% de las muestras fueron positivas, presentando una mayor frecuencia de residuos de Sulfametoxazol (38,5%) y Eritromicina (30,8%), seguidos por Penicilina y Estreptomicina, ambos con un 15,4%. Se concluye que existe un riesgo potencial para los consumidores. La detección frecuente de residuos de sulfametoxazol y eritromicina en carne de pollo peruana indica un riesgo sanitario global significativo, que demanda una vigilancia sanitaria rigurosa y la implementación de controles efectivos. Por consiguiente, es fundamental fortalecer la vigilancia sanitaria y asegurar la calidad de la carne de pollo, con el fin de mitigar la resistencia antimicrobiana y salvaguardar la inocuidad alimentaria tanto en Perú como a nivel global.
