July-September 2005 California Agriculture Table of Contents

COVER: This colored transmission electron micrograph (TEM) reveals prion fibrils in the brain of a cow infected with BSE (bovine spongiform encephalopathy) or mad cow disease. The elongated orange fibrils are believed to be aggregations of the abnormal prion protein, which is the disease agent. Although it has only been confirmed in two U.S. cows, BSE has caused policy and regulatory ripple effects involving producers, processors and consumers both here and abroad.

Tests for adulterated cattle feed based on DNA are faster and more sensitive, while those based on
antibodies are simpler and can be done in field.
