Abstract: The possible chemical/phytotoxin and microbial contamination of nine brands of pasta foods (macaroni, spaghetti and noodles) commonly consumed in Nigeria were investigated following identification of pesticide residues in Indomie noodles (a brand of pasta food) and contamination of baby foods (SMA) with some poisonous cassava materials. Enzymatic and spectrophotometric analysis of these foods for cyanide content indicate the presence of this compound ranging from 7.60-70.65 mg CN-kg-1. Chemical analysis of these foods showed the presence of alkaloids, tannins and saponins while microbial quality test indicated the presence of Salmonella sp., Rhizopus sp. and Staphylococcus aureus in three food samples. The implications of these findings are discussed from toxicological and food bioterrorism points of view.
