Strategic Diagnostics Inc. today announced that its Soya Test Kits, used for the detection of Genetically Modified Organisms (GMOs), have been validated as a test for compliance with the recently instated GMO food labeling regulations within the EU member countries.

In March 1999, the European Commission passed food labeling regulations stemming from public
concern about foods derived from genetically modified seeds. To enable consumer choice in
selecting food products, the European Commission now requires all food companies to label
products containing foods derived from GMO sources.

According to Richard C. Birkmeyer, President and CEO of SDI, ``The European Commission's
validation of our test allows SDI to offer the fastest, most cost-effective solution to facilitate
compliance requirements impacting the 22,000 food processors selling into the EU. Shipments of
our new kit began in the first quarter and we expect volumes to grow throughout 1999.''

Statistical Analysis

The Food Products Unit of the Institute for Health and Consumer Protection (IHCP), together
with the Reference Material Unit of the Institute of Reference Materials and Measurements (IRMM), both belonging to the European Commission's Joint Research Centre, validated this
protein-based test. It was validated using an IRMM Certified Reference Material and detects
Monsanto's CP4 EPSPS Protein expressed in Roundup Ready® Soybeans.

The results of the validation were published recently by IHCP. The table below summarizes the
results in terms of samples classified as positive (equal or greater than the arbitrary threshold of
2%) and samples classified as negative (below the arbitrary threshold of 2%).

(a) Statistical data interpretation revealed that with 99% confidence any sample scoring as negative contains less than 2% GMO and any positive sample contains at least 0.85% GMO. (Source of data: JRC-IHCP)

This data shows that the test was highly accurate.
