A survey of moulds and mycotoxins was performed on 99 rice samples taken from the Swedish retail market. The main objective to study mould mycotoxin content in basmati with a high fibre. Samples jasmine as well long-grain were also included. analysed for their ochratoxin (high-performance liquid chromatography (HPLC)), aflatoxin B(1), B(2), G(1), G(2) (HPLC, RIDA(R)QUICK), (traditional cultivation methods combination morphological analysis). majority sampled according European Commission Regulation 401/2006. Subsamples pooled mixed before milling both analyses milled rice. results showed that (71%) many (20%) contained detectable levels B(1) (level quantification = 0.1 microg kg(-1) rice). Two ten over regulated maximum limits 2 or 4 total aflatoxins. Aspergillus most common genus isolated, but Penicillium, Eurotium, Wallemia, Cladosporium, Epicoccum, Alternaria, Trichotecium found. presence flavus 21% indicates incorrect management during production storage implies risk growth subsequent aflatoxin. Rough estimates consumers may have an intake 2-3 ng bodyweight day(-1) alone. This shows is contaminant imported Europe.
