Kontroll i butik med fokus på Listeria monocytogens och hållbarhet av egentillverkade produkter
Sammanfattning: Listeria monocytogens causes the disease listeriosis, and the most common way the infection is spreading in the environment is believed to be through food. Listeriosis is a rare infection, but can cause serious symptoms in risk groups as the elderly, people with compromised immunesystems, pregnant women and their fetuses, mortality rate is 20-30%. There are two types of listeriosis, the first one is non-invasive listeriosis with a long incubation period and the low level of Listeria requires suffering from listeriosis. The second type is invasive listeriosis with a short incubation period and requires high levels of Listeria to induce the disease. The aim of this project was to analyze the prevalence of the pathogen Listeria monocytogenes in refrigerated ready-to-eat foods. Products, which are often associated with prevalence of Listeria, have extended shelf that makes it easier for the bacteria to grow. Samples were taken for analysis from Lomma municipality (10 samples). Also results from Kävlinge- and Vellinge municipality was used in this study. None of the samples showed any contamination from Listeria. The results of the analysis show that the stores own control works well and the requirement that the shops impose on manufacturers and control of the date of durability seem to be enough so that Listeria can be controlled.
