The presence of Listeria species in corn silage and raw milk produced in Southeast Region of Turkey

Bu çalışmanın amacı, mısır silajında ve çiğ süt örneklerinde bulunan Listeria türlerinin varlığının araştırılmasıdır. Türkiyenin Güneydoğu Bölgesinde bulunan 10 süt çiftliğinde mısır silajıyla yemlenen inek, koyun ve keçilerden elde edilen toplam 140 çiğ süt ve 90 mısır silajı örnekleri Listeria türleri bakımından analiz edildi. Silaj örneklerinin ikisinde (%2.2) ve çiğ süt örneklerinin üçünde (%2.1) L. monocytogenes, silaj örneklerinin beşinde (%5.5) ve süt örneklerinin de beşinde (%3.5) ise L. innocua izole edildi. Elde edilen sonuçlar, mısır silajları ve çiğ süt örneklerinin hayvan ve insan sağlığı açısından potansiyel bir risk taşıdığını göstermektedir. Silajlarda L. monocytogenes in çoğalmasının önlenmesi, aynı zamanda sütlerdeki Listeria ların azalmasına da katkıda bulunacaktır.

Türkiyenin Güneydoğu Bölgesinde üretilen mısır silajı ve çiğ sütlerde listeria türlerinin varlığı

The objective of this study was to investigate the presence of Listeria species in the corn silage and raw milk samples. A total of 140 raw milk samples obtained from cows, sheeps and goats fed with silage and 90 corn silage samples collected from 10 dairy farms in South- Eastern Region of Turkey were analyzed for Listeria spp. In the result, L. monocytogenes and L. innocua were isolated from 2 (2.2%) and 5 (5.5%) silage samples and from 3 (2.1%) and 5 (3.5%) raw milk samples, respectively. The results indicates that these are a potential risk for animals and public health. Prevention of growth of L. monocytogenes in silage will also contribute to reduction of Listeria spp. in milk.
