Fresh food from plants is fresh food that is consumed directly or after cutting, I have minimal processing. Therefore PSAT to be consumed must be safe from aspects of microbial contamination and physical chemical contamination. There are several types of pathogenic microbes, which can contaminate PSAT and can cause disease disorders. One microbe, which includes pathogenic microbes and potentially contaminates PSAT, is Listeria monocytogenes. Microbes Listeria monocytogenes are pathogenic in certain groups of people in small amounts.
To know the prevalence of Listeria monocytogenes, studies were carried out, by taking samples at locations, and selected commodities. The locations chosen are West Java, Banten and DKI Jakarta in two traditional markets in each province. While the selected commodities are bean sprouts, tomatoes and cabbage. Sampling was carried out by random method, with the population in accordance with the number of vegetable traders in that location. Testing of samples for Listeria monocytogenes contamination is carried out in accredited laboratories.
From the results of testing of 300 (three hundred) samples, consisting of 100 samples of bean sprouts, 100 samples of tomatoes, and 100 samples of cabbage, all test samples were declared negative or unexposed to Listeria monocytogenes.
