Colonization of Staphylococcus aureus in nasal cavities of food handlers in military
Abstract
Aims: The anterior nares constitute the primary ecological reservoir for Staphylococcus aureus in healthy individuals, with hands serving as the principal vectors for transmission. This study aimed to determine the prevalence of nasal S. aureus carriage and evaluate occupational risk factors among military personnel employed in food handling, personal care, and service delivery roles.
Methods: A retrospective analytical cross sectional study was conducted on 1,036 healthy male service personnels who presented to family medicine outpatient clinics in Ankara. Nasal swabs were cultured for S. aureus, and isolates were classified as methicillin susceptible (MSSA) or methicillin resistant (MRSA). Demographic variables and occupational sectors (service personnel, food preparation, and personal care) were recorded. Positive carriers received targeted topical antimicrobial treatment. Statistical analyses were performed using IBM SPSS v25.0, with significance defined as p < 0.05; chi square tests were utilized to assess associations, and 95% confidence intervals (CI) were provided for prevalence rates and odds ratios.
Results: The cohort median age was 21 years (QR = 4.0). Overall nasal colonization with S. aureus was 15.1% (n = 156). MSSA prevalence was 14.1% (n=146), while MRSA was identified in 1.0% (n = 10) of the sample, exclusively among service personnel. Occupational sector was a significant predictor of nasal carriage (?²= 22.635; p < 0.001), with service delivery staff exhibiting increased odds of colonization (OR = 3.307, 95% CI: 2.152-5.081).
Conclusion: In In this military cohort, moderate S. aureus colonization contrasted with infrequent MRSA carriage. However, the elevated risk in specific sectors necessitates targeted infection control. Despite debates over universal screening, these findings justify continued surveillance and decolonization for specialized military food service personnel to mitigate transmission and safeguard public health.
