Listeria turkumi Listeria monocytogenes va Listeria ivanovii kabi patogen turlarni o'z ichiga oladi , ikkinchisi issiq qonli hayvonlarda keng tarqalgan va tabiatda keng tarqalgan. Uning hamma joyda tarqalishi ushbu mikroorganizmning najas namunalarida sog'lom xo'jayinlar, tuproq, suv, chiqindilar, sabzavotlar va qayta ishlangan silos yoki oziq-ovqatdan (shuningdek ularning fabrikalaridan) ajratilishi bilan yaqqol ko'rinadi. Listeria monocytogenes ko'pgina bakterial oziq-ovqat patogenlaridan qattiq muhit sharoitlariga omon qolish, keng harorat oralig'ida (1–45°C) o'sish va keng pH oralig'ida (4,5–9,6), yuqori tuz konsentratsiyasi (10 dan 15% gacha NaCl) va juda past suv faolligi (aw = 0,94) ostida omon qolish qobiliyati bilan farq qiladi. Shuning uchun u turli xil oziq-ovqat mahsulotlarida o'sishi mumkin. Jamoat salomatligi nuqtai nazaridan , L. monocytogenes (asosan 1/2a, 1/2b va 4b serotiplari) odamlarda meningit, septitsemiya, abort va isitmali enterit kabi og'ir sindromlar uchun javobgardir. https://pmc.ncbi.nlm.nih.gov/articles/PMC4619823/#B4
