  text: "Microbial food safety is the master key for reducing illness caused by the
    consumption of foodstuffs. This demonstration therefore aims to use non-pathogenic
    surrogates to draw conclusions whether vegan ready-to-eat model food serves as
    a base for growth of pathogenic Escherichia coli and Listeria monocytogenes in
    vegan ready-to-eat meat substitute in case of a potential contamination, causing
    a reduction of food safety.\r\nPackages of ready-to-eat vegan meat substitutes
    were inoculated with certain level of non-pathogenic L. innocua and E. coli and
    incubated at varying environmental conditions before they were examined for changes
    in the physico-chemical properties.\r\nThe observed ability of the microbes to
    grow in the snacks may cause a reduction in food safety. This demonstration shows
    that these ready-to-eat-snacks may cause a reduction in food safety if the product
    studied is contaminated."
