Exhibit 99.1 NEWS RELEASE Company Contact: FOR IMMEDIATE RELEASE Arthur A. Koch, Jr. Chief Operating Officer (302) 456-6789 www.sdix.com Investor Relations Contact: Lippert/Heilshorn & Associates, Inc. William A. Walkowiak, CFA Klea Theoharis (212) 838-3777 klea@lhai.com Strategic Diagnostics Announces Collaboration with Molecular Circuitry, Inc. and McDonald's Corporation to Develop a Rapid Test for Animal Feed Additionally, Strategic Diagnostics to Market Molecular Circuitry's Rapid Pathogen Detex(TM) Products and Develop Lateral Flow (Strip) Tests for Salmonella, E. Coli, Listeria and Campylobacter Newark, Del., October 24, 2001 - Strategic Diagnostics Inc., (Nasdaq: SDIX) - a leading provider of antibody products and analytical test kits for the food safety and water quality markets, today announced that it has entered into a collaboration to develop a rapid test for unapproved animal remnants in animal feed. Concern over the presence of these materials has recently risen since these additives are believed to be linked to mad cow disease, which has affected meat production in Europe and sparked a recent outbreak in Japan. McDonald's Corporation is sponsoring the collaboration to develop a means to actively source only the highest quality meat products as part of their long-standing commitment to quality and safety. "McDonald's is absolutely committed to food safety, from the farm to the front counters of our restaurants," said Ken Koziol, McDonald's Global Quality Assurance Officer. He continued, "We are helping to fund this innovative research project because it represents another potential safety firewall in animal feed." Molecular Circuitry and Strategic Diagnostics will both contribute scientific resources to develop a commercial test kit under the collaboration. Mr. Herb Lotman, Chairman, President and CEO of Molecular Circuitry, remarked, "We are delighted to work with SDI on this vital project. We bring complementary expertise in microbiology and manufacturing capability that will position the group to achieve the finished test product's objectives, quick time-to-result and ease-of-use. Richard C. Birkmeyer, President and CEO of SDI, commented, "We are excited about the challenge of developing what could be the worldwide standard in testing for animal feed. SDI has done this before, in food and water testing, and we believe the team we have assembled here has the talent and resources to be successful. We expect to begin shipping the finished test in the first half of 2002." In additional news, SDI announced that it will market the Detex(TM) line of products developed and manufactured by Molecular Circuitry for food borne pathogens including Salmonella, E. Coli, Listeria and Campylobacter as well as Molecular Circuitry's newest hygiene test Detex(TM) RESI-CLEAN, an all-in-one monitoring device to detect food residues using glucose and lactose detection. The E. Coli test has been approved by the American Organization of Analytical Chemists (AOAC), and the other rapid pathogen tests are expected to be approved shortly. All of these products are targeted to the food manufacturing industry and will complement SDI's existing food safety products including tests for GMOs and mycotoxins. The food industry is increasingly concerned with food borne pathogen contamination and these tests are designed to meet the needs of a market that is spending more than $300 million for analytical tests today. In a further extension of the relationship with Molecular Circuitry, SDI announced it has acquired the rights to use the antibodies developed by Molecular Circuitry for the Detex(TM) rapid pathogen products to develop, manufacture and sell lateral flow (strip) tests for Salmonella, E. Coli, Listeria and Campylobacter. The projects to develop these tests are expected to run concurrently and take approximately six months to complete. After that time, SDI plans to launch a family of field-based test kits for the food manufacturing industry to complement the laboratory methods manufactured by Molecular Circuitry and sold by SDI. Also under the terms of this relationship, SDI will have access to Molecular Circuitry's extensive experience in analytical instrument manufacturing to support SDI's existing instrument business. Commenting on this additional news, Mr. Lotman said, "We believe the marketing and technical expertise Strategic Diagnostics brings to our collaborations will greatly enhance the reach our products and technologies are able to enjoy throughout the global food industry." Mr. Birkmeyer also commented, "We have been evaluating ways to enhance our existing relationships in the food industry. The quality of the Molecular Circuitry Detex(R) products will allow us to expand our relationships and build new ones based on confidence in analytical performance. We are delighted to have the opportunity to grow with Molecular Circuitry."
