Abstract

Mycotoxin contamination of staple foods represents a significant public health concern, particularly in countries lacking regulatory frameworks. This study aimed to assess mycotoxin contamination in maize, cowpeas and rice from local markets across Mauritania, using three detection methods (Charm II, ELISA and immunochromatographic tests). Samples were collected from 14 markets in six cities to analyse the presence of aflatoxins, ochratoxins, zearalenone and fumonisins. Preliminary results revealed significant contamination in cowpeas (64% positive for aflatoxins) and maize samples (fumonisins levels up to 50 times the EU limits in Nouakchott and Rosso markets). Rice samples showed minimal contamination across all tested mycotoxins. The obtained results highlight the need for monitoring and regulation of mycotoxin contamination in Mauritania, particularly considering climate change impacts on mycotoxin production and associated health risks.

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
