A total of 100 rice samples were collected from five provinces (Kars, Agri, Erzurum, Igdir, and Ardahan) in eastern Turkey. Samples were investigated for total aflatoxin (AF), aflatoxin B1 (AFB1), and ochratoxin A (OTA) levels. The results show that AF levels in 65 (65.0%), AFB1 levels in 35 (35.0%), and OTA levels in 38 (38.0%) of 100 samples were higher than the detection limits. AF and AFB1 levels in all samples were at tolerable limits. OTA levels in 3 samples have been found higher than the legal limits. The highest OTA level in the samples was found in winter season due to climatic conditions, especially relative humidity. Additionally, rice is mainly contaminated by AF, AFB1 and OTA. In Turkey, contamination in rice could be a relatively critical point for human health. Therefore, it is necessary to have an appropriate method for cereal preservation during distribution to consumers and markets.

The present study was conducted to investigate the incidence of Salmonella spp., Listeria monocytogenes and Escherichia coli O157 in 340 samples of meat and meat products (205 ground beef, 50 raw beef and 85 sausages) collected from producers and retailers in Istanbul. Salmonella spp. and Escherichia coli O157 analyses were performed acoording to ISO standarts, while Listeria monocytogenes was confirmed according to FDA methods. Salmonella spp. was detected in 1.18% samples. All samples were negative for L. monocytogenes and E. coli O157. The results indicate that meat and meat products may be contaminated by pathogens which can cause serious public health problems. Furthermore, the essential precautions should be undertaken to ensure improving the quality of production technology.
