Year: 2026
Type: conference-paper
Abstract: Layer eggs are a popular source of animal protein in society. The irresponsible use of antibiotics in poultry farming has the potential to leave residues in eggs, which can endanger consumer health, including triggering antimicrobial resistance. In Indonesia, the use of antibiotics as growth promoters in poultry is a common practice, and studies have reported concerning levels of residues in chicken meat and eggs from various regions.However, data on antibiotic residue contamination in eggs, particularly from traditional markets such as West Sulawesi, remains scarce. This study aims to investigated residues of oxytetracycline, penicillin, kanamycin, and tylosin antibiotics in layer eggs from traditional market Majene. A total of 90 eggs were taken using purposive sampling from nine sellers from Sentral market Majene. Samples then tested at the Maros Veterinary Center using a screening test method. Data were analyzed descriptively and presented in tabular form. The screening results showed that all samples (100%) were negative for oxytetracycline and penicillin antibiotic residues. However, all samples (100%) tested positive for residues of the antibiotic classes kanamycin and tylosin. Layer eggs from traditional market Majene were found to be free of oxytetracycline and penicillin residues, but contaminated with kanamycin and tylosin residues from Sentral market Majene. These findings indicate a shift in antibiotic use patterns and non-compliance withdrawal periods by farmers. Stricter supervision and education are needed to ensure the food safety of these products.
