Fungi and Aflatoxin Occurrence in Fresh and Dried Vegetables Marketed in Minna, Niger State, Nigeria

“…Further spoilage can occur during storage, handling and transportation as well as market [5]. Vegetable products that are susceptible to fungi growth can also be contaminated with aflatoxins [6].…”

Mycobiota and identification of aflatoxin gene cluster in marketed spices in West Africa

“…in Nigeria and studied potential drying options that will enhance product quality (Bankole, Osho, Joda, & Enikuomehin, 2005). Aflatoxin B1 was detected at levels above 5 mg/kg in 32.2% of the samples, while only 3.5% contained toxin above the 20 mg/kg Nigerian tolerance level for food (Bankole, Ogunsanwo, Osho, & Adewuyi, 2006). Natural occurrence of mycotoxins and fungal contamination on dried vegetables was investigated in many countries (Alghalibi & Shater, 2004;Begum, Lokesh, & Kumar, 2005;Hell, Gnonlonfin, Kodjogbe, Lamboni, & Abdourhamane, 2009;Mandeel, 2005;Nutsugah, Vibeke, Atokple, & Ayensu, 2004).…”

Mycoflora and absence of aflatoxin contamination of commercialized cassava chips in Benin, West Africa

“…Aflatoxins have been reportedly detected in among others a wide range of spices including black pepper, ginger, red paprika and cumin as reviewed by McKee (1995), in dried fruits from Yemen (Alghalibi & Shater, 2004), in diseased fresh tomato (Lycopersicon esculentum Mill) from Sokoto, Nigeria (Muhammad, Shedu, & Amusa, 2004), and in shelled melon seeds from Nigeria (Bankole, Ogunsanwo, Osho, & Adewuyi, 2006). Bassa et al (2001) showed that Aspergillus colonized yam chips and they found that 98% of samples of yam chips were contaminated with aflatoxins with levels ranging from 2.2 to 220 mg/kg.…”
