“…According to the U.S. Food and Drug Administration, hard or sharp foreign objects measuring between 7 mm and 25 mm are generally considered hazardous and may cause injuries ( Djekic et al, 2017 ). FM can be accidently present at any stage of the production process and carry destructive microbes, creating a more prominent ( Aladjadjiyan, 2005 ; Jia et al, 2024 ; Mathew, 2021 ). The FM sources mainly can be classified as intrinsic and extrinsic.…”

Ready-to-eat (RTE) foods are susceptible to contamination with methicillin-resistant Staphylococcus aureus (MRSA), presenting significant health risks to consumers. This study aimed to isolate, identify, and characterize MRSA from RTE foods in Delta, Nigeria, and assess their implications for consumer safety. Four hundred RTE food samples were collected from food outlets, and MRSA presence was determined using oxacillin resistance screening agar supplemented with polymyxin B and oxacillin. Polymerase chain reaction confirmed and characterized MRSA isolates for virulence potentials and antimicrobial resistance genes. Out of the 400 samples, 57(14.25%) tested positive for MRSA. The prevalence of virulence genes varied, with Panton-Valentine Leukocidin (pvl) detected in 40.51% of isolates, along with the detection of several staphylococcal enterotoxin genes. Antimicrobial resistance genes, including tetracycline (tetM, 43.04%), erythromycin (ermC, 32.91%), and methicillin (mecA, 100%; mecC, 29.11%) were detected. Staphylococcal cassette chromosome mec (SCCmec) typing revealed diverse profiles, with type V being predominant (32.9%). MRSA isolates exhibited resistance to multiple antibiotics, with 83.54% of them classified as multidrug-resistant. Extracellular virulence factors were common, with strong biofilm producers observed in 69.62% of isolates. These findings underscore the complexity of MRSA contamination in RTE foods, highlighting the need for enhanced surveillance and control measures to safeguard public health.
