Bluetongue virus, an incurable cattle and sheep killing disease, continues to spread through Europe.
Salmonella is challenging organism for calf operations, but the serotype Dublin is especially dangerous because of its unique hallmarks of multidrug resistance and ability to also cause severe illness in humans.
New cases in Italy, France and Spain underscore the importance of surveillance and preparedness in U.S. herds.

A 25-page criminal complaint alleges the researcher and her boyfriend were attempting to bring Fusarium graminearum into the country. The fungus causes significant diseases in a number of food crops, including corn, wheat, barley, soybeans and rice. Toxins from the fungus are harmful to humans and livestock.
NCBA’s Woodall says the goal is complete eradication — not just from the U.S., but from Mexico and Central America, ultimately pushing the fly back to its original range in South America.
