Workflows for proteomic and metabolomics analyses of fish mucus
January 27, 2020We have recently established workflows for the proteomic and metabolomic profiling of skin mucus in Atlantic salmon (Salmo salar). The epidermal mucus layer protects fish against harmful environmental factors and is an effective barrier between the fish and the biosphere. Since excreted proteins and small metabolites can mirror the health status of the fish, it…
Safer bread for children
January 3, 2020MycoSafeBread will develop Norwegian bread products tailor-made for young children; with an absolute minimum of the mycotoxin DON, while at the same time fulfilling state health recommendations with regard to whole grains and dietary fiber. Toddlers eat on average much more bread than adults per body weight, and the Scientific Committee on Food and Environment…

A Practical ELISA for Azaspiracids in Shellfish and Algae
February 21, 2019Azaspiracids (AZAs) are a group of natural algal toxins that appear periodically in shellfish. These toxins can cause food poisoning in humans and the first known poisoning episode happened in The Netherlands in 1995. The Irish shellfish consumed gave symptoms like stomach cramps, vomiting, severe diarrhea, and general nausea. Current methods for quantifying the regulated…
Bird mortality event associated with microcystins at Poplar Island, Maryland, USA
November 14, 2018More than 750 dead and dying birds were observed at the Paul S. Sarbanes Ecosystem Restoration Project at Poplar Island, Maryland, USA (Chesapeake Bay) in summer 2012. Avian botulism was suspected based on clinical signs. At the same time, a bloom of Microcystis was also ongoing in an impoundment on the island, and high levels…
Deoxynivalenol – nervous effects reconnaissance
August 1, 2018Data on neurotoxicological effects of the mycotoxin deoxynivalenol (DON), also called vomitoxin, are limited. Orally exposed laboratory (mice, rats) and domestic animals (pig, chicken) show behavioural changes such as feed refusal, increased locomotor activity and aggressive behaviour, and DON plasma concentrations at ppm-level result in vomiting in pigs and humans. Preliminary observations suggest that DON…
