The Board of Directors has approved amendments to  Regulation 1038.02 which will reduce the Exchange’s specified limit for deoxynivalenol (vomitoxin) in wheat deliverable against CBOT Wheat futures.  Under these revisions, the vomitoxin limit for deliverable wheat will change from 5 parts per million to 4 parts per million, effective for September 2006 and subsequent Wheat futures contract months.

Copies of the revised regulation are available from the Secretary’s Office.

Questions in this regard may be directed to CBOT Business Development,  Fred Seamon (312-347-3808) or David Lehman (312-347-3848).
