Abstract
Raw milk is susceptible to environmental pollution and considered to be one of the most perishable food items. The prevailing mode of contamination arises from the consumption of milk with digestive system, mucous secretions, and skin. The bacteria have the capacity to endure in milk for a period of ten days. The contamination of dairy products to polluted hand hygiene products is one of the contributing factors . The present study aimed to examine the effects of disinfectant solutions, specifically chlorine, with varying concentrations (1%, 2%, and 3%), on the contamination of personnel's hands. ANOVA, also known as one-way analysis of variance, was employed to assess the disparities in means. In order to compare the means at a significant level of 95%, Duncan's test was utilized. The findings exhibited that the presence of chlorine has a noteworthy impact on the abundance of microorganisms. Additionally, an investigation was conducted to assess the impact of MicroZ, alcohol at 68% and alcohol 96% on the reduction of Staphylococcus microbial population. By examining the central indicators and dispersion of the tested communities, the results showed that 68% alcohol has a greater effect on reducing the microbial population than microZ and 96% alcohol.
