Monitoring and Managing of Ergot Alkaloids in Cereal Grains: A Comprehensive Analysis of Analytical Challenges, Sampling Uncertainty, and Processing for Food Safety. [PDF]

open access: yesCompr Rev Food Sci Food Saf
ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Effects of Ergot Alkaloids on Liver Function of Piglets as Evaluated by the 13C-Methacetin and 13C-α-Ketoisocaproic Acid Breath Test

open access: yesToxins, 2013
Ergot alkaloids (the sum of individual ergot alkaloids are termed as total alkaloids, TA) are produced by the fungus Claviceps purpurea, which infests cereal grains commonly used as feedstuffs.

Cyclopropanation of carbon-carbon double bonds in ring d of ergot alkaloids [PDF]

open access: yes, 2013
Some ergot alkaloid derivatives containing a double bond in ring D have been reacted with diazomethane/palladium diacetate reagent to result in formation of a fused cyclopropane ring.

Impacts of cereal ergot in food animal production

open access: yesFrontiers in Veterinary Science, 2016
The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the 5th century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which ...

Effects of Heating, Pelleting, and Feed Matrix on Apparent Concentrations of Cereal Ergot Alkaloids in Relation to Growth Performance and Welfare Parameters of Backgrounding Beef Steers

open access: yesToxins, 2022
As the contamination of cereal grains with ergot has been increasing in Western Canada, studies were undertaken to evaluate the impacts of heating (60, 80, 120, or 190 °C) alone or in combination with pelleting on concentrations of ergot alkaloids ...

Ergot Alkaloid Contents in Hybrid Rye are Reduced by Breeding

open access: yesAgriculture, 2021
Contamination by ergot caused by the phytopathogenic fungus Claviceps purpurea is a constant threat to the whole rye value chain. Ergot alkaloids (EA) produced within the fungal sclerotia are toxic for humans and animals and are subjected to strict ...

The Usage of Ergot (Claviceps purpurea (fr.) Tul.) in Obstetrics and Gynecology: A Historical Perspective

open access: yesToxins, 2021
In the past centuries consumption of bread made of ergot-infected flour resulted in mass poisonings and miscarriages. The reason was the sclerotia of Claviceps purpurea (Fr.) Tul.—a source of noxious ergot alkaloids (ergotamine and ergovaline).

Immersion of grains in a liquid along an inclined plane [PDF]

open access: yesE3S Web of Conferences, 2021
Grain material delivered from combine harvesters to post-harvest processing points is a mixture of grain, weed and harmful impurities. Toxic ergot sclerotia are among the harmful impurities. Modern grain cleaning machines do not provide the separation of
