A Meta-Analysis of the Global Prevalence Rates of Staphylococcus aureus and Methicillin-Resistant S. aureus Contamination of Different Raw Meat Products

Abstract

Previous research has indicated that raw meats are frequently contaminated with Staphylococcus aureus , but data regarding the pooled prevalence rates of S. aureus and methicillin-resistant S. aureus (MRSA) contamination in different types of raw meat products (beef, chicken, and pork) and across different periods, regions, and purchase locations remain inconsistent. We systematically searched the PubMed, EMBASE, Ovid, Web of Science, and HighWire databases to identify studies published up to June 2016. The STROBE guidelines were used to assess the quality of the 39 studies included in this meta-analysis. We observed no significant differences in the pooled prevalence rates of S. aureus and MRSA contamination identified in various raw meat products, with overall pooled prevalence rates of 29.2% (95% confidence interval [CI], 22.8 to 35.9%) and 3.2% (95% CI, 1.8 to 4.9%) identified for the two contaminants, respectively. In the subgroup analyses, the prevalence of S. aureus contamination in chicken products was highest in Asian studies and significantly decreased over time worldwide. In European studies, the prevalence rates of S. aureus contamination in chicken and pork products were lower than those reported on other continents. The pooled prevalence rates of S. aureus contamination in chicken and pork products and MRSA contamination in beef and pork products were significantly higher in samples collected from retail sources than in samples collected from slaughterhouses and processing plants. These results highlight the need for good hygiene during transportation to and manipulation at retail outlets to reduce the risk of transmission of S. aureus and MRSA from meat products to humans.

Prevalence and Molecular Characterization of Enterotoxin- and Antibiotic Resistance-Encoding Genes in the Methicillin-resistant Staphylococcus aureus Recovered From Poultry Meat

“…Incidence of MRSA in samples examined in Brazil [35], Turkey [36], Egypt [37], Germany [38] and Denmark [39] was 21.72%, 30%, 40.80%, 71.50% and 52.00%, respectively. Similar records were also reported from Australia [40], United Kingdom [41], and United States [42].…”

Staphylococcus aureus Isolated From Retail Meat and Meat Products in China: Incidence, Antibiotic Resistance and Genetic Diversity

“…This result indicated that the processing can reduce the contamination of S. aureus . There was a previous study which summarized by Ou et al ( 2017 ) in 2017, it was collected 39 studies of the prevalence rates of S. aureus contamination by different types of raw meat products across different periods, regions, and sampling locations and found that the prevalence of S. aureus contamination in chicken products was highest in Asian. In this study, it was similar to this research result, which showed the prevalence of S. aureus contamination in 67.9% of raw poultry and 60.9% of quick-frozen poultry.…”

Effect of interactions of plant phenolics with bovine meat proteins on their antibacterial activity

“…S. aureus is a Gram-positive bacterium, it has an extraordinary ability to colonize and survive for long periods in a wide variety of environmental niches (Ou et al, 2017). Its presence in food is often attributed to insufficient hygiene when handling the product (Da Silva Malheiros, dos Passos, Casarin, Serraglio, & Tondo, 2010).…”
