Although AFTs are generally not found in temperate-region foods, global warming has affected typical temperate-region climates, potentially permitting the contamination of foods with AFT-producing Aspergillus flavus (A. flavus). Here we investigated the AFT production in rice during storage under natural climate conditions in Japan. We examined AFTs in brown rice and rough rice artificially contaminated with A. flavus for 1 year in Japan, and we subjected AFTs in white rice to the same treatment in airtight containers and examined the samples in warm and cold seasons, simulating the storage of white rice in general households. In the brown rice, AFTs increased after 2 months (March) and peaked after 9 months (October). The AFT contamination in the rough rice was minimal. After the polishing and cooking of the brown rice, AFTs were undetectable. In the white rice stored in airtight containers, AFTs increased after 1 month (August) and peaked after 2 months (September). Minimal AFTs were detected in the cold season. Thus, AFT contamination in rice may occur in temperate regions following A. flavus contamination. The storage of rice as rough rice could provide be useful for avoiding AFT contamination. en-copyright= kn-copyright= en-aut-name=SugiharaSatoshi en-aut-sei=Sugihara en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoiHiroyuki en-aut-sei=Doi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatoMasahiko en-aut-sei=Kato en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsudaToshihide en-aut-sei=Tsuda en-aut-mei=Toshihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IkedaSatoru en-aut-sei=Ikeda en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Animal Pharmaceutical Sciences, Kyushu University of Health and Welfare kn-affil= affil-num=4 en-affil=Department of Oral Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Human Ecology, Okayama University Graduate School of Environmental and Life Science kn-affil= affil-num=6 en-affil=Department of Medical Technology, Graduate School of Health Sciences, Okayama University kn-affil= en-keyword=Aspergillus flavus kn-keyword=Aspergillus flavus en-keyword=aflatoxin kn-keyword=aflatoxin en-keyword=rice kn-keyword=rice en-keyword=temperate region kn-keyword=temperate region en-keyword=storage kn-keyword=storage END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=‰––‘Žσ—e‹@\:ƒJƒGƒ‹γˆτ_Œo‚ΜNa‚¨‚ζ‚ΡMg‰ž“š‚Ι‘Ξ‚·‚ιNi‚Μ‘‹­Œψ‰Κ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=”ό“‘ƒO kn-aut-sei=”ό“‘ kn-aut-mei=ƒO aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=‰ͺŽR‘εŠw END
