Studies on the Toxic Substances in Barley Infected with Fusarium spp

Abstract: Using the procedure employed for the separation of fusarenon and nivalenol, toxic substances were separated from cereal grains infected with Fusarium in the crop field of Kagawa-ken in 1970. Production of the toxic substances in culture filtrates of the isolated strain was also determined. The results are summarized as follows:(1) Fusarium spp., Alternaria spp., Aspergillus spp. and Penicillium spp. were isolated from moldy grains of barley and wheat. Fusarium roseum or related species were found to be a majority of casual fungi.(2) Moldy grains mainly contained “Rd-toxin”, mp. 149. 5-151°C, and nivalenol, mp. 224-226°C, both toxic to mice and protozoa and the former was considered as a newly found mycotoxin having a scirpene nucleus.(3) Phytotoxic butenolide, mp. 115-117°C, hardly detectable in the grains, and Rd-toxin were separated from culture filtrates of the isolated Fusarium roseum strain, whereas nivalenol was not detected.

Aflatoxin Contamination in Foods and Foodstuffs in Tokyo: 1991-1996

Abstract: Aflatoxins were determined in 3054 samples of foods or foodstuffs, including cereals, nuts, beans, spices, dairy products, dry fruits, and edible oil. Samples were collected in Tokyo from 1986 to 1990. Aflatoxins were found in rice products, adlay, corn, crude sugar, peanut products, pistachio nuts, brazil nuts, sesame products, butter beans, white pepper, red pepper, paprika, nutmeg, and mixed spices. The highest incidence of aflatoxin contamination was observed in nutmeg (80%), and the highest level of aflatoxin B1 was observed in pistachio nuts (1382 ppb).

Migration of Bisphenol A from Polycarbonate Products

Abstract: The migration of bisphenol A from food contact polycarbonate products was investigated by HPLC with a quantitation limit of 0.5ppb. The migration was affected by the test conditions and it increased in the order of water and 4% acetic acid at 60°C, 30min<20% ethanol at 60°C, 30min

Enteropathogenicity of Diarrhetic Shellfish Toxins in Intestinal Models

Abstract: Enteropathogenicity of diarrhetic shellfish toxins (DST) was evaluated in rabbit intestinal loops, mouse intestinal loops and suckling mice, by using the methods established for the detection of bacterial enterotoxins. Crude toxin of DST (cr-DST) was prepared by acetone extraction from scallops (Patinopecten yessoensis) implicated in the poisoning outbreaks in Osaka in 1978 and 1982. Individual DSTs such as dinophysistoxin-1 and -3 (DTX-1 and DTX-3), pectenotoxin-1 (PTX-1) and okadaic acid were also tested on suckling mice for diarrheagenicity.The rabbit loop injected with 8 MU of cr-DST showed significant fluid accumulation in 18 hours. The mouse loop injected with 0.8 MU of cr-DST also showed significant fluid accumulation in 6 hours. In the suckling mouse test, positive results were observed with 0.1 MU of cr-DST in 4 hours. The small intestines with fluid accumulation in the loop tests were sectioned and stained with hematoxylin-eosin for histopathological studies. Destruction of epithelium and edema of the lamina propria were observed. In the suckling mouse test, DTX-1, DTX-3 and okadaic acid showed positive results, whereas PTX-1 did not.From these data, we concluded that DST shows enterotoxic activities in these animal models and that okadaic acid, DTX-1 and DTX-3 are diarrheagenic.
