Microbiological quality assessment of ice cream marketed in Thrissur city with special reference to Salmonella spp.

The research was undertaken to determine the microbiological quality of ice cream sold in retail shops in Thrissur city. The study aimed to evaluate the safety and hygiene of ice cream, sold in the retail market. Ten samples of ice cream each from six different brands were meticulously collected and microbiological parameters like Total viable count (TVC), coliform count and presence of Salmonella spp. were investigated. The mean TVC varied from 2.29 ±0.06 to 4.55 ±0.03 log10 CFU/g indicating the overall microbial load present in the ice cream, while mean coliform count ranged from 2.0 to 2.83±0.04 log10 CFU/g which served as an indicator of faecal contamination. Total viable counts of all the sixty samples analysed were within the standards set by Food Safety and Standards Authority of India (FSSAI). However, coliform count of one brand exceeded FSSAI guidelines. Presence of Salmonella spp. was not identified in any of the samples analysed. While the majority of the samples analysed complied with the established safety standards, the elevated coliform count in one brand indicates a need for improved quality control measures. This finding highlights the relevance of continuous monitoring and compliance to food safety standards to ensure consumer health and safety. Ongoing surveillance and adherence to food safety regulations are essential to maintain the microbiological quality of ice cream and protect public health.
