4-Deoxynivalenol is one of the most prevalent mycotoxins in grain-based food and feed products worldwide. Conjugation of deoxynivalenol to glucuronic acid and elimination via the urine appears to be the major metabolism pathway, although with differing efficiency in different species. In order to make pure deoxynivalenol glucuronides for analytical(More)
Enniatins are cyclic hexadepsipeptidic mycotoxins with ionophoric, antibiotic, and insecticidal activity. Enniatin B (EnnB), the most important analogue, is produced by many Fusarium species and is a common contaminant in grain-based foods. The compound's cytotoxic potential has been shown in different experiments; however, the mode of action has not been(More)
Food allergy is an important issue in the field of food safety because of the hazards for affected persons and the hygiene requirements and legal regulations imposed on the food industry. Consumer protection and law enforcement require suitable analytical techniques for the detection of allergens in foods. Immunological methods are currently preferred;(More)
Enniatins are cyclic hexapeptidic mycotoxins produced by fungi growing on field grains, especially in wet climates. They show considerable resistance to food and feed processing technologies and might cause intoxication of humans and animals. Enniatins are also under exploration as anticancer drugs. The observed difference of in vitro and in vivo toxicities(More)
The parasitic nematode Anisakis simplex occurs in fish stocks in temperate seas. A. simplex contamination of fish products is unsavoury and a health concern considering human infection with live larvae (anisakiasis) and allergic reactions to anisakid proteins in seafood. Protein extracts of A. simplex produce complex band patterns in gel electrophoresis and(More)
The Norwegian Food Allergy Register was established at the Norwegian Institute of Public Health in 2000. The purpose of the register is to gain information about severe allergic reactions to food in Norway and to survey food products in relation to allergen labelling and contamination. Cases are reported on a voluntary basis by first line doctors, and(More)
Several cases of neurological disease in dogs after poisoning by food- and feed-borne Penicillium toxins in Norway during the last years have uncovered a lack of knowledge regarding the toxicity and mechanism of action of neuroactive mycotoxins. In the present study, the lowest tremor-inducing dose after single oral administration of penitrem A to mice was(More)
Trichothecenes are a large family of chemically related mycotoxins. Deoxynivalenol (DON), T-2 and HT-2 toxins belong to this family and are produced by various species of Fusarium. The H295R steroidogenesis assay, regulation of steroidogenic gene expression and reporter gene assays (RGAs) for the detection of androgen, estrogen, progestagen and(More)
Enniatins (ENNs) are hexadepsipeptidic mycotoxins produced by Fusarium species. They occur in mg/kg levels in grain from Northern climate areas. Major ENNs such as ENN B and B1 have shown considerable cytotoxicity in different in vitro test systems. To adequately assess exposure and in vivo toxicity the toxicokinetic properties need to be investigated. The(More)
