“…The microbial richness and diversity in D0 were markedly higher than those of the remaining three groups, which might be due to the microbial contaminations generated during a series of processes, such as slaughtering, transportation, sale, etc. [6,13].

To investigate the diversity and dynamics of microorganisms in Chinese fresh beef (CFB) without acid discharge treatment during cold storage, high-throughput sequencing was employed to analyze the CFB refrigerated for 0, 3, 7, and 10 days. The results showed that the community richness of the fungi and bacteria decreased significantly. However, the diversity decreased in the early stage and increased in the later stage. At the phylum level, Ascomycota (74.1–94.1%) and Firmicutes (77.3–96.8%) were the absolutely dominant fungal and bacterial phyla. The relative abundance of both fungal and bacterial phyla displayed a trend of increasing and then decreasing. At the genus level, Candida (29.3–52.5%) and Lactococcus (19.8–59.3%) were, respectively, the dominant fungal and bacterial genera. The relative abundance of Candida showed a trend of increasing and then decreasing, while Lactococcus possessed the opposite trend. KEGG metabolic pathways analysis suggested that carbohydrate metabolism, membrane transport, and amino acid metabolism were the major metabolic pathways of bacteria. Bugbase prediction indicated the major microbial phenotype of bacteria in CFB during cold storage was Gram-positive (17.2–31.6%). Correlation analysis suggested that Lactococcus, Citrobacter, Proteus, and Rhodotorula might be the main microorganisms promoting the production of off-flavor substances in CFB. This study provides a theoretical basis for the preservation of Chinese fresh beef.

“…As a vital part of the livestock industry that provides meat for millions of people worldwide [2][3][4], it is crucial to address several aspects of slaughterhouses' health and safety procedures. These aspects, including butchering and preparing animals on bare floors contaminated with blood and feces, pose a risk to the public [5][6][7][8]. Studying meat microbes can help determine which slaughtering techniques are most successful in minimizing and controlling contaminants during the process.…”

“…Studying meat microbes can help determine which slaughtering techniques are most successful in minimizing and controlling contaminants during the process. Additionally, the microbiological characteristics of meat can serve as a good indicator of its sanitary value [8][9][10]. The lack of proper slaughtering facilities, sanitation, and corpse processing may be responsible for the elevated levels of bacteria in meat.…”

Inadequate hygienic conditions and poor handling are the primary causes of contamination in abattoirs. This study aimed to identify and molecularly detect pathogenic bacteria in sheep meat at slaughterhouses in Riyadh City, Saudi Arabia. Additionally, the study evaluated the sensitivity of these bacteria to various antimicrobials. In total, 150 samples were collected three times every two months from November 2021 to March 2022 from four abattoirs located in the south, west, east, and north of Riyadh. Pathogenic bacteria were separated using selective media, and the Vitek 2 system was utilized to identify all species and test their response to antibiotics. PCR was employed to detect virulence genes. The four pathogenic bacteria identified in all samples were Escherichia coli (12%), Klebsiella pneumoniae (9.3%), Salmonella enterica (7.3%), and Pseudomonas aeruginosa (6.6%). Abattoir D had a high number of bacteria isolated in January. K. pneumoniae and S. enterica exhibited resistance to ampicillin. S. enterica also demonstrated resistance to gentamicin, ciprofloxacin, and trimethoprim/sulfamethoxazole. P. aeruginosa was resistant to tigecycline. PCR results indicated positive tests for the E. coli gene FimH, the P. aeruginosa genes plcH and toxA, and the K. pneumoniae gene mrkD. Pathogenic bacteria with positive results for virulence genes have the potential to cause contamination and human diseases. To improve quality and reduce contamination, the government must address the issue of providing adequate and safe water for activities in all abattoirs in Riyadh City.
