Microbial control measures for soft ice cream in franchise brands: A comparative analysis of microbial analysis and manufacturing practices

The aim of this study was to establish a complementary direction of the franchise food hygiene guideline to control microbial risks. We evaluated current measures of preventing microbial spoilage and ensuring microbiological safety of food in the food franchise industry. Manufacturing practices were assessed using microbiological analyses, third‐party food safety audits, and existing hygiene guidelines. Microbial load indicators of food, manufacturing processes, work environment, and workers were also analyzed to track microbial proliferation. We audited manufacturing practices and processes and analyzed the cleaning and sanitation clauses. We found high contamination of heterotrophic bacteria and detected coliforms in some products. There was no direct contamination by food handlers, and the sterility of raw materials was satisfactory. The main issues were structural complexities of equipment, which hindered cleaning and disinfection, and disinfection practices of franchise brands. Store‐level microbial control may be compromised due to the industrial nature of small stores operating collectively. We thus issued complementary guidelines. Improved collective microbiological safety may be ensured through implementation of the revised cleaning and sterilization regulations.
