“…S. aureus in floor samples in this study (40%) was higher than 25% in Nigeria [44] and 33.33% in Ethiopia [36]. The prevalence of S. aureus in wall samples (30%) was higher than 8% in Turkey [45] and 1.3% in Nigeria [46]. The differences in the results can be associated with lack of cleaning, improper handling, and contamination from polluted air [47].…”

Cross-contamination of animal carcasses and their contact surfaces at any level of the meat handling process is a significant factor in the production of high-quality meat. The present study was carried out to investigate the hygienic status at El-Qurein abattoir, Sharkia Governorate, Egypt. Microbial indicators for the hygienic measures including total aerobic plate count (APC) and Staphylococcus count (TSC) were investigated. In addition, the prevalence of Staphylococcus species among abattoir samples and Staphylococcus aureus antimicrobial susceptibility testing were also detected. The obtained results revealed that the bacterial contamination in abattoir samples was as follows; abattoir effluents > floors > walls > brisket > rump with mean values of 5.89 ±0.01, 5.65±0.02, 5.06±0.01, 4.87±0.01, and 4.41±0.05 log10 CFU/cm 2 , respectively for APC, while, 4.92 ± 0.02, 4.80 ± 0.02, 4.70 ± 0.02, 4.61 ± 0.03, and 4.38 ± 0.05 log10 CFU/cm 2 for TSC, respectively. The disc diffusion test of S. aureus isolates revealed its resistance to most of the tested antibiotics with high multiple antibiotic resistance (MAR) indices. It was concluded that the hygienic measures at El-Qurein abattoir were inadequate. This study suggested the necessity of the application of appropriate food safety practices inside the abattoir and the adoption of personal hygienic measures among abattoir workers.

“…The isolates from this point can be colonized in the environment by virtue of the production of biofilm, which increases the possibility of cross-contamination while improving the viability. Gungor et al (2021) isolated S. aureus from environmental samples from pastirma production line and reported that environmental cross-contamination of products was possible. The findings of this study indicated that due to the cross-contamination between the environment and the carcass in the chilling room, the decontamination and hygienic strategies of the chilling room environment should be strengthened.…”

Staphylococcus aureus (S. aureus) is a common zoonotic foodborne pathogen that poses a serious threat to the microbial control of meat processing, especially the multidrug resistant (MDR) strain. This study aimed to investigate the prevalence, antimicrobial susceptibility, virulence genes, biofilm formation ability (BFA), and molecular types of S. aureus isolated from two beef‐processing plants in China. The results revealed that the prevalence of S. aureus was 17.1% (60/350), including one methicillin‐resistant strain. The chilled carcass showed the highest detection rate among the seven sampling points. The isolates exhibited high resistance to penicillin (88.3%) and lincomycin (80.0%), and 75.0% of the isolates showed multidrug resistance (MDR). All isolates carried hla and clfa and critical toxin genes (seb, pvl, and tst) were also detected. Additionally, 96.7% of isolates exhibited strong and moderate BFA. The isolates were typed by Multilocus Sequence Typing (MLST) and Staphylococcus Protein A (spa) typing methods, resulting in nine different types for each method. The predominant type was ST7‐t091, accounting for 68.3% of the isolates. Our research suggests that there may be a critical control point in the chilling room, and the high MDR rate and strong BFA increase the difficulty of control and the risk of transmission.
