Comparative Study of Ochratoxin A Exposure through the Intake of Cereal Products in Two Climatic Moroccan Regions.

The present study aims to compare ochratoxin A (OTA) exposure through the intake of three cereal derivative products (bread, pasta and semolina) in two different Moroccan climatic regions (littoral and continental). OTA weekly intakes from cereal products were calculated using a deterministic approach for each region. Results showed a statistically significant difference ( < 0.

Exposure assessment to ochratoxin A through the intake of three cereal derivatives from the Moroccan market.

Previous studies reported the contamination of cereals products with OTA in Morocco. Given bread, pasta and semolina are staple consumed food in the country, this study aims to assess the OTA exposure levels for the adult consumers in the country through cereal derivatives intake, by using a deterministic model based on the crossover of consumption and contamination data of 457 cereals products samples. The study also set out to determine under what conditions the OTA contributions from these 3 cereal derivatives alone were enough to cause a real public health problem in the country.
