<![CDATA[Methicillin-Resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococcus (VRE) are major contributors to healthcare-associated infection, yet data from primary care clinics remain limited. This study assessed environmental contamination in eight clinics in the Klang Valley, Malaysia, and evaluated associated environmental factors. Samples were collected from environmental surfaces and equipment in Medical Officer and Patient Treatment Rooms, then cultured and tested for antimicrobial susceptibility. Environmental parameters, including temperature, relative humidity, air movement, and room density, were measured. Data were analyzed using Kruskal–Wallis, Mann–Whitney, and multiple linear regression analyses. MRSA was detected on 19.8% of environmental surfaces (patient treatment beds (47.3%) and side tables (31.6%)), and 2.1% of equipment surfaces. No VRE was detected; however, Vancomycin-Sensitive Enterococcus was identified in several samples. Significant variation in MRSA contamination across sampling sites was observed (χ² = 25.664, p-value = 0.007). Regression analysis showed that room density (β = −3.285, p-value = 0.006) and temperature (β = −7.922, p-value = 0.012) were significant predictors of aerobic colony counts (R² = 0.157). The detection of MRSA on high-touch surfaces highlights occupational exposure risks in PHC. Strengthened infection prevention and control measures, targeted cleaning strategies, and improved spatial management are urgently required to mitigate environmental transmission.]]>
