Occurrence of ochratoxin A in spices commercialized in Abidjan (Côte d'Ivoire).

Ochratoxin A (OTA) is a mycotoxin produced mostly by several species of Aspergillus and Penicillium. OTA is nephrotoxic in all animal species in which it has been tested and is cancerogenic in rodents. It is associated with Balkan endemic nephropathy.

Effect on blood pressure of a dietary supplement containing traditional medicinal plants of Côte d'Ivoire.

Ethnopharmacological Relevance: A medicinal composition containing salt (sodium chloride) is given as a traditional dietary supplement to hypertensive patients (TDSHP) in Côte d'Ivoire. It consists of whole plant of Bidens pilosa (Asteraceae) and fresh leaves of Moringa oleifera (Moringaceae).

Aim Of The Study: The aim of this study was to establish the scientific basis for the use of this traditional recipe rich in sodium chloride in hypertension settings.

Impact of industrial treatments on ochratoxin A content in artificially contaminated cocoa beans.

Ochratoxin A (OTA) is a mycotoxin mainly produced by mould species of the genera Aspergillus and Penicillium, which grow on a variety of agricultural products. OTA-contaminated foodstuffs pose a major health hazard to consumers, including human and animal. In Cote d'Ivoire, numerous studies are being carried out to find the best way of preventing OTA contamination of cocoa raw material.

Co-occurrence of aflatoxin B1, fumonisin B1, ochratoxin A and zearalenone in cereals and peanuts from Côte d'Ivoire.

This survey examined 30 samples of rice (n = 10), maize (n = 10) and peanuts (n = 10) from Côte d'Ivoire for aflatoxin B1, fumonisin B1 and zearalenone using immunoassays, and ochratoxin A using a validated HPLC method with fluorescence detection. In Côte d'Ivoire, as in other countries, several mycotoxins are present in the same commodities. These mycotoxins are from different structural families: aflatoxin B1, fumonisin B1, zearalenone and ochratoxin A, normally produced by fungal species from Aspergillus, Penicillium and Fusarium genera.

Ochratoxin A in human blood in Abidjan, Côte d'Ivoire.

Ochratoxin A (OTA) produced by Aspergillus and Penicillium genera contaminates a diversity of foods including cereals; cereals-derived foods; dry fruits; beans; cocoa; coffee; beer; wine; and foodstuffs of animal origin mainly poultry, eggs, pork and milk, including human breast milk. OTA is nephrotoxic to all animal species studied so far and most likely to humans, who show the longest half-life for elimination of this toxin among all species examined. Among other toxic effects, OTA is teratogenic, immunotoxic, genotoxic, mutagenic and carcinogenic, all of which lead to life-threatening pathologies through several molecular pathways.
