Poster Session Tournas, V.H. [1], Niazi, N.S. [2], Katsoudas, E.J. [3]. Fungal profiles of selected grains and grain products from U.S. retail. A total of 85 grain and grain product samples (including corn meal, corn muffin mix, popcorn, various types of rice, and self-rising, unbleached and whole wheat flour) from U.S. retail were tested for fungal contamination levels and profiles using conventional plating as well as molecular methods. The results of this study showed that over 90% of wheat flour and corn product samples and 73% of rice samples tested carried live fungi. Popcorn carried the highest fungal levels reaching 2.8 x 105 colony forming units (cfu) per gram followed by corn meal (reaching 2.4 x 105 cfu/g). Mould and yeast counts (MYC) in rice and wheat flour reached 2.0 x 103 and 1.9 x 103, respectively. The predominant moulds in wheat flour were aspergilli and fusaria found in 50 and 46% of samples, respectively; while Fusarium spp. were the most frequent contaminants of corn-based products found in 74% of the samples followed by penicillia (present in 44% of tested samples). Rice, on the other hand, contained mainly Aspergillus, Fusarium and yeasts (each found in 21% of the samples).
