“…These findings are in agreement with some of previous studies in Argentina [24]. Although a lower occurrence rate was reported by Zinedin et al [20] (30%), and Imperato et al [25] high incidence rate of OTA in raising were more frequently observed in raisins analyzed in Germany [26], Sweden [27], Canada [28], Egypt [29] and Turkey [15,30]. Only one of the 15 dried apricot and two of the 20 dried date samples was contaminated with OTA at the 2.8 and 2.5 ng/g Level ( Table 2), which was below the maximum tolerance accepted by the European Commission (10 ng/g) [12].…”

“…Although different extraction and detection techniques were used, similar incidence rate of OTA in dried figs have been reported by Bircan [15] (18% with a maximum concentration of 24.37 ng/g), and Senyuva et al [16] from (14% and 15%; with a maximum concentration of 26 ng/g). However, some author have reported lower incidence rates of OTA in dried figs, such as 3% [17] and 0.1% -0.6% [18], whereas Guler and Heperkan [19] (48%), Zinedine et al [20] (65%), Lamanaka et al [21] (95%) reported much higher occurrences of OTA in dried figs.…”

“…The natural drying, which may consists in direct exposition of the fruit to the sun, is widely used especially in rural area in Iran. During the process of fruit drying, the sugar is concentrated as the moisture content decreases resulting in an almost selective medium for xerotolerant moulds such as A. niger section nigri species [20]. Among black aspergilli, A. carbonarius is the most important as OTA producing isolate observed more frequently [34].…”

“…Furthermore, a correlation between dietary exposure to AFs and the incidence of human liver cancer in some areas, especially in Africa and Asia, has been shown (Hill et al 1986). OTA is predominantly found in cereal grains, cereal products, legumes, oilseed, coffee beans and feed (Zinedine et al 2007). The frequency of contamination of rice analysed for OTA was 72%.…”

One hundred unpackaged rice samples, each weighing 500 g, were randomly collected at retail stores and open markets in the largest rice growing area (Thrace) in Turkey and analysed for mould counts, predominant mould genera, moisture content and mycotoxin levels. Mould counts ranged from 1.0 × 10(1) to 1.5 × 10(4) cfu/g in 70 of 100 samples, and the correlation between moisture content and mould count was significant (p ≤ 0.05). Aspergillus spp. and Penicillium spp., potential mycotoxin producers, were the dominant moulds. In one area from which samples were collected, the mycotoxin content of rice was found to be positively correlated with moisture content; samples with higher moisture also contained higher numbers of moulds. The levels of total aflatoxins, aflatoxin B1 and ochratoxin A were higher than the maximum tolerable limits (4, 2 and 3 μg/kg, according to the EC Regulation and the Turkish Food Codex) for 32, 14 and 30 of 100 rice samples, respectively. This is the first comprehensive report of ochratoxin A levels in rice grown in Thrace, Turkey.

“…For example, harvesting of cereals with a high content of water or their inefficient drying or storage under humid conditions may result in higher levels of OTA in them (JØrgensen & Jacobsen 2002). Out of cereals, for example rice is an aquatic plant and is usually harvested at high moisture levels (Zinedine et al 2007). If rice crop is infected by ochratoxigenic fungi and if the environmental conditions during storage are favourable, OTA will be produced .…”

Cicoňová P., Laciaková A., Máté D. (2010): Prevention of ochratoxin A contamination of food and ochratoxin A detoxification by microorganisms -a review. Czech J. Food Sci., 28: 465-474.Ochratoxin A is a mycotoxin produced by several fungal species of the genera Aspergillus and Penicillium. This mycotoxin is nephrotoxic, immunosupressive, teratogeni, and carcinogenic to animals and has been classified as a possible human carcinogen. Human exposure to ochratoxin A is worldwide. Ochratoxin A occurs in a variety of foods. An ideal method for minimisation of the health risk that this mycotoxin poses is the prevention of food contamination. When the contamination occurs, the hazard associated with the mycotoxin presence in the food must be eliminated. Various microorganisms such as bacteria and microscopic fungi have been tested for their abilities to prevent ochratoxin A contamination or detoxify foods. Biological control by microorganisms is studied widely, therefore the objective of this article is to provide an overview of the recent development in the biological control of ochratoxin A contamination.
