the number of vegetable processing plants has been increased during recent years in iran as many other countries. on the other hand, fresh vegetable products are susceptible to microbial contamination after harvest, processing, handling, packing and distribution. the aim of this study was to determine and evaluate the level of microbial load of vegetables during different cleaning steps in a fr...

Background: Cucumber is one of the vegetables that are widely preserved by fermentation in brine. Vegetables such as cucumber are normally not washed in the commercial centers and this causes microbial growth during fermentation. At the beginning of the fermentation process, lactic acid bacteria, depending on the environmental conditions, begin to grow. The aim of this study was to compare the ...

BACKGROUND Although the U.S. Environmental Protection Agency has a long history of using risk-based approaches for regulatory purposes, pollutant limits for pathogens in biosolids are not currently based on quantitative risk assessments. OBJECTIVES We developed and demonstrated a risk-based methodology for assessing the risk to human health from exposure to pathogens via biosolids. MATERIAL...

background and objectives: pre-requisite programs (prps) are “primary conditions and requirements essential for haccp operations, which are crucial in food safety programs”. the present study was conducted to evaluate the impact of implementation of prps on the microbial parameters of pasteurized milk (according to the national standard of iran). effectiveness of haccp operation requirements an...

The spatial context of microbial interactions common in natural systems is largely absent in traditional pure culture-based microbiology. The understanding of how interdependent microbial communities assemble and coexist in limited spatial domains remains sketchy. A mechanistic model of cell-level interactions among multispecies microbial populations grown on hydrated rough surfaces facilitated...
