Microbiological Quality and Organochlorine Pesticide Residue in Commercially Available Ready-To-Eat Raisins

Abstract

Microbiological quality and organochlorine pesticide residual contamination in raisins in a restricted area of Lucknow city, India was assessed in 20 samples. Total bacterial count was found in both open and packed raisin samples within the acceptable range (105–<106). The presence of food pathogens like Salmonella spp. and Enterobacteriaceae was detected more in open samples whereas Staphylococcus spp. and Pseudomonas spp. were absent. Lactobacilli spp. was found in all open samples and two packed samples. Presence of OCP residue was also found below the MRL although low levels of α-HCH and γ-HCH were detected in samples. The study shows presence of spoilage and pathogenic microorganisms as well as OCP residue within permissible limits which was more in open samples than in packed ones.
