Abstract
Aim and background
The objective of this study was to investigate the presence of aflatoxin M1 (AFM1) in milk, yogurt, and cheese samples collected from Tabriz, Iran. Additionally, the study conducted a risk assessment related to the consumption of milk and dairy products within Tabriz city.
Study method
For this study, 56 samples (raw milk, pasteurized milk, ultra-high temperature milk (UHT), traditional yogurt, pasteurized yogurt, traditional cheese, and pasteurized cheese) were collected randomly in Tabriz from December 2021 to March 2022. The analysis was carried out using liquid chromatography, which was equipped with a fluorescence detector. The estimated dietary intake (EDI) and the hazard index (HI) were calculated for the risk assessment.
Results and discussion
AFM1 was detected in all samples. The highest concentration of AFM1 was observed in traditional cheese (P < 0.05). The lowest concentration was observed in UHT milk and there were no significant differences between the various milk types and pasteurized yogurt (P > 0.05). Moreover, in all samples, the levels of AFM1 were below the maximum limit permitted by Iranian national standards. AFM1 levels in traditional yogurt exceeded the European Union's permissible limit in 25% of the samples. The HI in all samples was less than one for both adult and child consumers, except for milk samples for children, which were more than one and indicated a medium risk. In conclusion, the levels of contamination in milk and dairy products and risk assessment appear not to pose a public health risk to Tabriz consumers.
期刊介绍:
Toxicon has an open access mirror Toxicon: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. An introductory offer Toxicon: X - full waiver of the Open Access fee.
Toxicon''s "aims and scope" are to publish:
-articles containing the results of original research on problems related to toxins derived from animals, plants and microorganisms
-papers on novel findings related to the chemical, pharmacological, toxicological, and immunological properties of natural toxins
-molecular biological studies of toxins and other genes from poisonous and venomous organisms that advance understanding of the role or function of toxins
-clinical observations on poisoning and envenoming where a new therapeutic principle has been proposed or a decidedly superior clinical result has been obtained.
-material on the use of toxins as tools in studying biological processes and material on subjects related to venom and antivenom problems.
-articles on the translational application of toxins, for example as drugs and insecticides
-epidemiological studies on envenoming or poisoning, so long as they highlight a previously unrecognised medical problem or provide insight into the prevention or medical treatment of envenoming or poisoning. Retrospective surveys of hospital records, especially those lacking species identification, will not be considered for publication. Properly designed prospective community-based surveys are strongly encouraged.
-articles describing well-known activities of venoms, such as antibacterial, anticancer, and analgesic activities of arachnid venoms, without any attempt to define the mechanism of action or purify the active component, will not be considered for publication in Toxicon.
-review articles on problems related to toxinology.
To encourage the exchange of ideas, sections of the journal may be devoted to Short Communications, Letters to the Editor and activities of the affiliated societies.
