Aflatoxins in various food from Istanbul, Turkey

Area of Science:

• Food Science
• Mycotoxicology
• Public Health

Background:

• Aflatoxins are toxic secondary metabolites produced by Aspergillus fungi.
• Food contamination by aflatoxins poses a significant risk to human health.
• Regulatory limits for aflatoxins are established to protect consumers.

Purpose of the Study:

• To determine the levels of total aflatoxin and aflatoxin B1 in food samples from Istanbul, Turkey.
• To assess the prevalence of aflatoxin contamination exceeding legal limits.
• To identify specific food items with high aflatoxin concentrations.

Main Methods:

• Analysis of 62 food samples collected from Istanbul.
• Quantification of total aflatoxin and aflatoxin B1 using [Specify analytical method if known, e.g., HPLC, ELISA].
• Comparison of detected levels with established legal limits.

Main Results:

• Total aflatoxin content averaged 1.7 μg/kg in dried American cucumber, squash, tomato, okra, and saffron.
• Aflatoxin B1 levels averaged 1 μg/kg in five dried vegetables, two teas, and three spice samples.
• A significant 76% of all tested samples exceeded legal limits for total aflatoxin.
• Chestnut (232.9 μg/kg), nutmeg (206.1 μg/kg), and sumac (182.5 μg/kg) showed the highest contamination levels.

Conclusions:

• A high prevalence of aflatoxin contamination exceeding regulatory standards was observed in Istanbul food samples.
• Certain food items, including dried vegetables, spices, and nuts, are particularly susceptible to high levels of aflatoxin.
• Regular and effective food monitoring and control are crucial to mitigate public health risks associated with aflatoxin exposure.
