THE ROCKY MOUNTAIN REGIONAL MEETING

OF THE AMERICAN CHEMICAL SOCIETY

JUNE 9-12 1996,

DENVER, COLORADO, USA

Mycotoxin Symposium

The Symposium on Mycotoxins, sponsored by the 13th Rocky Mountain Regional ACS Meeting, organized by Mary W. Trucksess, Division of Natural Products, Food & Drug Administration, Washington, DC 20204, will be held in Sheraton Denver West, Lakewood, Colorado, June 9-12, 1996. This symposium will include topics of current interest: mycotoxins and human health, sampling for mycotoxins, analytical methods (for fumonisins, deoxynivalenol, aflatoxins, and other fusarium toxins), rapid multimycotoxin methods, mycotoxin problems in China, and distribution of mycotoxins after dry milling.
