Mold Flora of Traditional Cheeses Produced in Turkey
2016
Musa Yalman | Seda Özdikmenli Tepeli | Nükhet Nilüfer Demirel Zorba
In our country, there are many cheese types that are produced traditionally. Cheeses which produced from cows, sheep and goat milk that matured with spontaneous growth of molds present in livestock skins, pots and similar environments are among them. They are produced traditionally in Mediterrian, Central and Eastern Anatolia regions. Molds that grow spontaneously in cheeses could create public health risk because of their secondary metabolites. Penicillium spp. are the most isolated mold from these cheeses and Penicillium roqueforti is determined as the dominant species. Furthermore, Aspergillus, Alternaria, Mucor, Geotrichum, Cladosporium species have been isolated. It is very important to control the ripening conditions and starter strain selection since some strains were reported as mycotoxin producers. In this review, it has been tried to give general information about traditional production of mold-ripened cheese in Turkey and the mold flora found in traditional cheeses. In addition, public health risk of these cheeses is reported.
Afficher plus [+] Moins [-]Türkiye’de Üretilen Mısırlarda Mikotoksin Düzeylerinin ve GDO Varlığının Araştırılması

Ülkemizde mısır üretimindeki artış bir yandan sürerken, bir yandan da dünyada mısırın soyadan sonra en çok genetiği değiştirilmiş ürün olması nedeniyle tüketicinin mısır ile ilgili algısı her geçen gün daha olumsuz olmaktadır. Genetiği değiştirilmiş mısırın potansiyel olumsuz etkileri tartışılmakta iken, mısırda insan sağlığı için gözden kaçmaması gereken en büyük tehdit mikotoksinlerdir. Bu çalışmada, Türkiye’nin 24 ilinde bulunan 552 köyün 634 tarlasından toplanan mısır numuneleri GDO, aflatoksin B1, toplam aflatoksin, fumonisin B1, fumonisin B2, T-2 toksin, HT-2 toksin, zearalenon ve deoksinivalenol yönünden incelenmiştir. Tarama yapılan mısır numunelerinin hiçbirinde transgenik elemente rastlanmamıştır. Analiz edilen 634 numunenin sadece bir tanesinde Türk Gıda Kodeksi limitinin üzerinde aflatoksin B1 miktarına rastlanmış, numunelerin toplam aflatoksin değerleri Türk Gıda Kodeksi limitinin altında çıkmıştır. Paçal oluşturulan numunelerin hiçbirinde T-2 toksin, HT-2 toksin, zearalenon ve deoksinivalenol tespit edilmezken, fumonisin tespit edilen numunelerin toplam fumonisin miktarı Türk Gıda Kodeksi limitinin altında bulunmuştur. Bu sonuçlar, yerli üretim mısırların gıda güvenliği açısından uygun standartları sağladığını göstermektedir.
Afficher plus [+] Moins [-]Organic Animal Production and Mycotoxins
2018
Nurcan Çetinkaya
Organic animal production; is a form of production without using any chemical inputs from production to consumption. In organic livestock production; organic breeding, feedstuff and animal nutrition conditions are stated in the Regulation on the Principles and Implementation of Organic Agriculture. Organic animal products must be prevented from recontamination. There are three different contamination hazards; biological (mold-toxins and pathogenic micro-organisms), chemical (pesticide residues), and physical (broken metal or glass, etc.). Molding and mycotoxin formation in organic feeds is one of the most important problems since they adversly affect animal health and toxines pass through the products. Since any chemical method cannot be applied to the organic feedstuffs especially in the struggle with mycotoxin in organic animal production, this should be considered in the measures to be taken and in the systems to be applied and the system should be planned to include organic agriculture. Countries that have established HACCP and ISO 22000 food safety management systems are able to avoid the problem of mycotoxin pollution in organic animal foods. The establishment of the feed safety system based on HACCP principles and its application in production have been made compulsory by Feed Hygiene Regulation issued in Turkey since 2011. In this review, the relationship between organic animal production and mycotoxin, and the precautions to be taken are discussed.
