EXHIBIT 23.1 INDEPENDENT AUDITOR'S CONSENT The Board of Directors Alfacell Corporation We consent to the use of our report included herein and to the reference to our firm under the heading "Experts" in the prospectus. Our report dated October 4, 2000 contains an explanatory paragraph that states that the Company has suffered recurring losses from operations and has limited liquid resources, which raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of that uncertainty. /s/ KPMG Short Hills, New Jersey July 25, 2001
