“…Occurrence of various endotoxins (aflatoxin, T-2 toxin, DON, ZEN, and fumonisin) except BUT and FUS C have been reported by using conventional methods like HPLC and ELISA in Turkey (17,18). Chemotyping studies of F. graminearum and F. culmorum isolates are focused on class B trichothecene detection (14,19).…”

“…Doğan and Beyazıt (10) detected 62% AFB1 residue below 10 µg/kg and 8% AFB1 residue above 10 µg/kg in 100 feed samples collected from Kars province in Turkey. Şahindokuyucu Kocasarı et al (34) showed that the most common mycotoxin found in the feed stuff was aflatoxin (60%) in Burdur province, Turkey. Kaya et al (22) investigated mycotoxin residues in 1200 feed and feed stuff collected from different regions of Turkey by thin layer chromatography 1.08% of these samples were contaminated by mycotoxins.…”

Summary:In this study total aflatoxin (AF) and aflatoxin M1 (AFM1) contamination in feed and milk samples obtained from the dairy cow farms in Kırıkkale region were studied. A total of 154 dairy cow feed and 154 raw milk samples were obtained from the villages (Delice, Keskin, Sulakyurt, Bahşılı, Yahşihan, Çelebi, Karakeçili, Balışeyh) and central of Kırıkkale province, Turkey, between the years June 2012-August 2013. The quantitative analysis of total AF and AFM1 in the collected samples were carried out using an enzyme-linked-immunoassay (ELISA) with commercial kits (HELICA biosystems inc.). Total AF was detected in all feed samples and also AFM1 contamination was found in all of the milk samples. In 5 of 154 feed samples the total AF's were above 20 µg/kg. In none of the milk samples AF was above the legal limit. The mean AF residue level for concentrated feed was 6.43±7.01 µg/kg, and ranged from 0.20 µg/kg to 28.80 µg/kg. The mean AFM1 residue for milk samples was 1.73±2.20 ng/L, and ranged from 0.08 ng/L to 10.11 ng/L. In conclusion although all of the milk samples were contaminated with AFM1, the amounts were within the legal limits that are allowed in milk. On the other hand in 3.25% of the feed samples, total AF was above 20 µg/kg. The occurrence of AFM1 may not be considered as a possible risk for public health. Strategies and monitoring programs to prevent aflatoxin contamination is recommended.Keywords: AFM1, dairy cattle feed, ELISA, raw milk, total aflatoxin.

“…The results of our study are in accordance with these studies (15)(16)(17). Many screening studies have been conducted to determine mycotoxin residues (4,(18)(19)(20). Oğuz et al (21) collected 150 feed samples from Konya and Mersin, and found that only 4 samples were contaminated with AFB1 (0.5-1 ppb).…”

IntroductionMycotoxins are the toxic metabolites of fungi; they are associated with significant damage to organ systems. The harmful effects of mycotoxins include suppression of immunity, hepatotoxicity, carcinogenicity, nephrotoxicity, and neurotoxicity (1). Major mycotoxins threatening the public health are aflatoxins (AFs), ochratoxins (OTs), and fumonisins (2). AFs are considered to be the most toxic and carcinogenic mycotoxins that pose a risk to both animals and humans (3). AFs are produced by fungi of the genera Aspergillus and Penicillium (such as A. flavus, A. parasiticus, and P. puberulum). Some major members of AFs include AFB1 (the most potent member), AFB2, AFG1, and AFG2. Depending on the sensitivity of the animal and the amount of the received toxins, AFs can lead to acute, subacute, and chronic poisoning. A small amount of toxins in the animal feed can reduce the growth rate and the feed consumption ratio, thus decreasing the number of animal products and carcass quality, and causing immune system suppression in animals (4). OTs are a group of mycotoxins produced by A. ochraceus (also known as A. alutaceus) and Penicillium viridicatum. The most important members of this group are OTA, OTB, OTC, the methyl ester of OTA, and the ethyl ester of OTB. Of these, OTA is the most common pollutant found in feed and feed ingredients. OTA is very resistant to heat and affects protein, DNA, and RNA synthesis in the body (2-4). Fumonisins, which are synthesized by fungi of the genus Fusarium, have been reported to have negative effects on lipid metabolism (5). Fumonisins also have hazardous effects on the liver, cardiovascular system, kidneys, and embryos, as well as teratogenic effects. The ingestion of fumonisin-contaminated corn may even lead to cancer in humans (6).Seasonal changes and climate variations can have an impact on food safety hazards at various stages of the food chain, from primary production to consumption. Most scientists accept the influence of weather on AF contamination. Appropriate temperature and water activity are critical for the production of mycotoxins and mycotoxin producing fungi. In general, if the temperature increases in cool or temperate climates, AF contamination becomes more problematic. In areas where storage facilities are controlled, it is possible to prevent postharvest contamination problems; however, this increases the cost and causes economic loss (5,7).
