When fires ripped through suburban subdivisions in Santa Rosa last October, they may have done more than reduce homes to ashes. By incinerating all kinds of materials — insulation, electronics, furniture, cleaning products, pesticides — at very high temperatures, they could have created unknown or previously unrecognized health hazards in the smoke and ash. Researchers from �°��ϲ��Ļ��Ϣ Davis, are trying to figure out just what is in that ash and air.

Against the Tide: A Fish Adapts Quickly to Lethal Levels of Pollution

Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 in the journal Science. Atlantic killifish living in four polluted East Coast estuaries have adapted to levels of highly toxic industrial pollutants that would normally kill them.

Veterinary food-safety lab gets $1.89 million boost for toxicology testing

IET WebDev — December 23, 2015 - 12:00am

The California Animal Health and Food Safety Laboratory System, based at the University of California, Davis, has received a $1.89 million, five-year grant from the federal Food Emergency Response Network to support its food-safety efforts.

The new grant will increase the capacity of the lab’s toxicology services to respond to contamination threats to the American food supply involving food animals and to carry out day-to-day diagnostic and early detection activities.
