INTRODUCTION: The Lebanese diet, rich in cereals, pulses, and dairy, is highly vulnerable to mycotoxin contamination due to the country's temperate climate and humidity. The ongoing economic crisis in Lebanon has intensified food insecurity and malnutrition, increasing health risks related to mycotoxins.
METHODS: A nationally representative cross-sectional study assessed exposure to multiple mycotoxins, including aflatoxin B1 (AFB1), aflatoxin M1 (AFM1), ochratoxin A (OTA), deoxynivalenol (DON), T-2, HT-2, zearalenone (ZEA), and fumonisins (FUM) among 442 Lebanese adolescents (mean age 14.56 years) and related risks, with attention to associations with stunting and thinness. Data were collected via a food frequency questionnaire and 24-h recall, whereas contamination levels were sourced from previous studies.
RESULTS: Results showed a stunting prevalence of 4.07% and a thinness at 2.71%, with adolescents consuming an average of 317.56 g/day of cereals. Contamination analysis revealed that AFM1 in dairy products averaged 0.09 μg/kg, exceeding the European limit, and AFB1 in thyme exceeded Lebanese standards at 11.63 μg/kg. Overall, mytotoxin exposure levels were concerning and were associated with MOE values below 10,000, indicating a major public health risk. Notably, AFB1 exposure was linked to additional estimated liver cancer cases per 100,000 people per year. After adjusting for gender, age category, residence, adolescent education, parents' education, and monthly income, stunting was significantly associated with the estimated daily intake of AFB1 (β = -0.07, t = -3.65, p < 0.001), OTA (β = -0.09, t = -4.619, p < 0.001), and DON (β = -0.001, t = -3.373, p = 0.001).
DISCUSSION: Thinness was associated with exposure to all mycotoxins; the strongest were observed for DON, OTA, AFM1, and AFB1. These findings underscore the urgent need for control measures and public health policies to mitigate mycotoxin exposure among Lebanese adolescents.
