Broiler chickens or broilers are the cheapest source of animal protein that can be obtained apart from eggs. The high demand for broiler chicken meat is fulfilled because modern broilers grow rapidly and are maintained massively and intensively. Massive maintenance systems make the spread of disease easier. Treatment of bacterial diseases using inappropriate antibiotics can lead to antibiotic resistance. This study aims to look at the antibiotic resistance of Escherichia coli (E. coli) bacteria from broiler chickens. E coli bacteria were isolated from 34 samples of broiler chicken cecum taken from several large traders in the city of Makassar. The E. coli isolates were then tested using Kirby-Bauer's diffuse disc method on 5 types of antibiotics from 5 classes of antibiotics namely: Ampicillin (β-lactam); Tetracycline (Tetracycline); Gentamicin (Aminoglycosides); Enrofloxacin (Flouroquinolone); Sulfamethoxazole-Trimethroprim (Sulfonamide). The inhibition zone formed was interpreted using the CLSI 2018 standard. The results of this study were 79.4% of the samples resistant to Ampisillin, 85.3% resistant to Tetracycline, 61.8% resistant to Sulfamethoxazole-Trimethroprim, 76.5% resistant to Enrofloxacin and 52.9% were resistant to Gentamicin. With 91.18% of the sample being resistant to at least 2 types of antibiotics.

Contamination in food products can occur at any stages, from pre-production to producer, post-production to the product being distributed and presented to consumers. This study aims to determine the extent of the application of sanitation hygiene at the critical control points of Salmonella sp. so that the description of the conditions and the relationship between the presence in the chicken egg chain in farms until it is ready to be distributed. This research was conducted on 72 laying hen farms in the same area using a cross-sectional study design. Data collection methods are observations and interviews regarding sanitation hygiene practices that include the application of sanitation hygiene to eggs, feed, cages, and workers. Critical control points of Salmonella sp. the spread, which was observed consisted of poultry cages, egg collection process, egg evaluation, and chicken eggs ready for distribution. The results showed that sanitation hygiene practices in layer farms were mostly implemented in cages (67%) and eggs (56%), while the application of sanitation hygiene was not widely applied in the feed (20%) and workers (28%).
