Foodborne illness and deaths caused by pathogenic microorganisms have become important public health concerns in recent years.Dangerous pathogens can easily contaminate foods and cause foodborne diseases. Ready-to-eat products like salad and ice cream are especially vulnerable and can cause foodborne diseases because these foods are not exposed to any further treatments before consumption to eliminate dangerous microorganisms. The nutritional value of ice cream is high due to its milk content. Therefore, it is a good nutritious source for the development of pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Salmonella, Listeria monocytogenes, Shigella, Campylobacter jejuni, and Bacillus cereus (Gundogan & Avci, 2014).Many foodborne diseases due to the contamination of L. monocytogenes in dairy products such as ice cream were reported all over the world (Callejón et al., 2015;Dean & Zottola, 1996;Silk et al., 2013). Furthermore, Crawford (2007) and Scallan et al. (2011) reported that every year, approximately 2,500 cases of listeriosis caused by L. monocytogenes occurs and it is one of the most important causes of death due to foodborne diseases in the United States.
