<p>Meat and meat products offer a favorable environment for the growth and multiplication of various microorganisms because of the high nutrient content. The aim of the present study was to detect the level of microbiological contamination of retail chicken meat samples in the Mullana (Ambala) territory of Haryana, India. A total of fifty raw chicken meat samples were randomly collected from various retail butcher shops (<i>n</i> = 10) in the Mullana area of Ambala district. All the isolates were confirmed by MALDI-TOF MS and screened for antibiotic susceptibility testing by Kirby Bauer disk diffusion method for a set of antimicrobials. The results showed a total of eight genera of contaminating bacteria and a total of 38 bacterial isolates were retrieved from the collected 50 meat samples. The total aerobic bacterial count range was between 2.93 × 10³ CFU/gm and 3.48 × 10⁶ CFU/gm. Nearly 44% of chicken meat samples were contaminated with <i>P. mirabilis</i>. The majority of isolates were resistant to amoxicillin–clavulanic acid and trimethoprim–sulfamethoxazole (73%, 16/22). This study further substantiates the potential of new bacterial species found in contaminated chicken meat samples as a source of food poisoning, which is a global public health concern.</p>
