Denmark Reports Cases of Bluetongue Disease That Can Be Fatal to Sheep but is Harmless to Humans

Denmark reported Tuesday cases of bluetongue in the country's east, a non-contagious, insect-borne viral disease that is harmless to humans but can be fatal for so-called ruminant animals—mainly sheep but also cows and goats.

Authorities said the virus known as bluetongue serotype 3, or BTV-3, has been crawling up through Europe in the past weeks. It's spread by midges that carry the virus and that are typically found in .

It has been reported on the island where Copenhagen is located. Cases have also been reported in Germany, the Netherlands and France, Danish authorities said.

The first case in Denmark was recorded in early August, on a Danish farm with  and cows near the German border. Danish authorities have also informed the European Commission about the case and animals have since been vaccinated to try and contain the spread.

The Danish Veterinary and Food Administration said tests results are upcoming from the island of Funen in central Denmark, where it is also suspected.

Video: Porcine Gut Models in Nutrition Research - Dr. Li-Hsuan Chen



In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
