“…Optimum conditions are 16-24 % moisture at 20-38 ºC. However, it is reported that aflatoxins production can also take place at temperatures as low as 7-12 ºC 17 . After harvest, if grains are not dried quickly or during storage remains at moisture high enough, mycotoxins such as aflatoxins may Aflatoxins contamination in foods, which causes the economic loss and threats to public health, is a world wide problem encountered from time to time in most countries of the world.…”

Food is one of the most intimate and important components of our chemical environments. Good food is not only expected to look fresh and tasty but it must be free from all contaminants. Mycotoxins are natural food and feed contaminants mainly produced by moulds of genera Aspergillus flavus, Aspergillus paraciticus, Aspergillus nomius 1 . Mycotoxin contaminated food consumption is associated with several cases of human poisoning or mycotoxicosis and some times resulting in death 2 . Fungus invades, most commonly, cereal foods in hotter countries due to which shortage of food was faced 3 .Wheat (Triticum aestivum L.) is the leading food grain of Pakistan and being the staple diet of the people. Wheat provides energy, which is a rich source of carbohydrates, magnesium, manganese, proteins, vitamin, fiber and minerals. Different by-products are formed from raw wheat that are used in bakeries for different food products. It occupies a central position on agricultural policies and economics of the country. It contributes 12.5 % to the value added in agriculture and 2.9 % to GDP. Wheat is cultivated on an area of 8 million hectares and its annual production was about 18.47 million tons in 2008-2009. At farm level, the storage consists of mud bins, metallic bins, concrete rooms, jute bags and wooden boxes. Whole

“…In ruminants, protozoa and bacterial enzymes in the anterior stomach hydrolyze OA, resulting in phenylalanine and non-toxic OTα formation (Battacone et al, 2010;Mobashar et al, 2012). However, enzymes involved in the metabolism of phenylalanine indirectly have adverse effects on lipid peroxidation and mitochondrial respiration (Steyn & Stander, 1999).…”

Mycotoxins, which are produced by some fungi under improper storage conditions before or after harvesting in plant products, cause acute or chronic toxicities. Ochratoxin A (OA) which is also one of the harmful mycotoxins pose a threat to animal and human health. This study was carried out in order to determine OA levels in mixed feed and feedstuffs materials used in livestock enterprises throughout Sivas province. The 59 mixed feeds and 30 feedstuffs materials collected from different enterprises was analysed. Ochratoxin A concentrations were quantified using immunoassay (ELISA). In result, OA was found to be positive in 64 (71.91%) of the 89 samples analysed, whereas OA was not found in 25 samples (28.09%).
