Potential hazardous human exposure to aflatoxin M1 (AFM1) via consumption of milk and milk products has been demonstrated by many researchers. The aim of this study was to investigate the presence of this mycotoxin in buffalo and cow milk samples in the city of Afyonkarahisar, Turkey. For this purpose, 126 buffalo and 124 cow milk samples were collected from dairy farms in Afyonkarahisar province. AFM1 levels were determined by high-performance liquid chromatography with tandem mass spectrometric detection. Although AFM1 was not detected in cow milk samples, AFM1 was found above the limit of detection (<0.008–0.032 µg/L) in 27% (34 out of 126) of the buffalo milk samples. The results of this study indicated the importance of continuous surveillance of commonly consumed milk or milk product samples for AFM1 contamination in Turkey.

The present study aimed to determine the antibacterial, antioxidant, cytotoxic activities and element levels of Verbascum lasianthum Boiss. ex Bentham. The free radical scavenging activity, total phenolic content, total antioxidant capacity, total oxidant capacity levels were analyzed as the antioxidant parameters. Seven bacteria and one yeast strains were used to determine the antimicrobial activity. The cytotoxic effects of plant extracts were determined using A549, MCF-7, HepG2 and SH-SY5Y cell lines. The findings demonstrated that the antioxidant activity increased with an increase in the phenolic content of extracts. This species is rich in bio-elements such as Fe, Cu, Mn, Zn, and Mg. Different concentrations of extracts could have antibacterial activity. This plant had an apparent cytotoxic effect only in the A549 cell line and increased the proliferation in other cell lines. The findings demonstrated that plant could be used alone or as a supplement to the current treatment protocols in diseases due to their antioxidant, antibacterial and cytotoxic effects. However, it is recommended that Verbascum L. species intended for use in therapy should be procured from areas where there is no soil pollution or organic farming is preferred.

Organophosphate (OP) pesticides via consumption of milk and milk products induce hazardous effects on human health. Considering their risk to human health, the determination of organophosphate pesticide levels in dairy products is very important. Until now, there has been limited data available on the occurrence of organophosphate pesticides in dairy products in Turkey. The aim of the present study was to investigate the presence of malathion and malaoxon residues in commonly consumed buffalo and cow milk products in the city of Afyonkarahisar, Western Turkey. For this purpose, 75 buffalo and 75 cow milk samples were collected from the city. Malathion and malaoxon levels were determined by means of liquid chromatography/tandem mass spectrometry. In the study, neither malathion nor malaoxan was detected in buffalo and cow milk samples. In conclusion, survey studies were performed continuously for organophosphate pesticide contamination in consumed milk samples and products in Turkey
