Maple Leaf Foods launches DNA pork traceability program

TORONTO, ONTARIO, January 27, 2004 — Maple Leaf Foods Inc.
(TSX: MFI) today announced that having successfully completed research and
development into producing a DNA traceability program for pork, it is set to
launch the first commercial application of this technology, with far-reaching
benefits for food safety and the Canadian pork industry.

The DNA traceability system will allow Canadian pork
marketed anywhere in the world to be traced back to the maternal sow, providing
the Canadian pork industry with a major competitive advantage and an essential
point of difference for the “Made in Canada” brand. Canada has set the
international gold standard for pork, based on our superior quality, exclusion
of growth promotants and sustainable environmental practices. DNA traceability
provides further assurance to consumers that they are getting the best pork
from the world’s healthiest hogs, raised under the third-party audited Canadian
Quality Assurance program.

The system will be implemented at one of Maple Leaf’s
plants in the spring of 2004, and initially provide fully traceable pork
products to the Japanese market by the fourth quarter of 2004. Maple Leaf plans
to make the commercial traceability system available for use by the Canadian
pork industry after the initial implementation.

“In an era of growing concerns over food safety and
increasing demands for full traceability of meat products, this breakthrough
will deliver an added level of food safety assurance,” said Michael H. McCain,
President and Chief Executive Officer of Maple Leaf Foods. “By using DNA, which
is nature’s bar code, this system is uniquely positioned to trace product from
the consumer to the farm of origin, where current methods cannot. DNA
traceability will provide a calling card for Canadian pork that no other
country can currently match.”

Maple Leaf worked with Pyxis Genomics Inc. in the research
and development phase of the DNA traceability project to develop a panel of
highly informative genetic markers. By combining well-proven fingerprinting
technology, enhanced with its own innovations, Pyxis successfully developed a
gene panel that provides the foundation for the pork traceability system, which
can accurately and rapidly trace pork products back to the farm of origin.
Although the traceability system was developed for pork products, it is broadly
applicable to other animal-species.

The traceability system involves obtaining a blood sample
from the maternal sow, which is then DNA-typed. The DNA information is then
entered into a database linked to the farm of origin information. Producers can
then update the database directly with the dates of birth of each litter.

“The success of identifying the gene panel significantly
enhances our ability to provide live animal tracking systems that can directly
link store-bought product back to its origin in a matter of hours, instead of
days or weeks,” said Dr. Lawrence B. Schook, President and Chief Executive
Officer of Pyxis Genomics Inc. “This is critical in an industry seeking to
offer the highest standards of assurance to consumers in containing food safety
incidents when they occur.”

Maple Leaf and Pyxis have chosen Orchid BioSciences to
develop an assay to analyze the genetic marker panel and to implement a quality
accredited laboratory process that will deliver rapid, high-throughput DNA
analysis. Orchid is a leading provider of genetic testing with a proven record
in the agricultural sector through its scrapie genotyping service, processing
over half a million samples at its U.K. facility last year.

“Orchid’s proprietary genotyping and service testing
expertise ensures we can deliver cost-effective, accurate and rapid high-volume
genetic analyses for animal food safety applications,” said Paul J. Kelly,
M.D., Chief Executive Officer, Orchid BioSciences, Inc. “Orchid has been a
pioneer in developing and implementing new technologies to advance the utility
of DNA identity testing and we look forward to contributing to the commercial
success of Maple Leaf’s traceability program.”

Maple Leaf and Pyxis have chosen IBM Canada Ltd. to create
and implement the comprehensive database featuring a computerized search engine
that will quickly match DNA from a piece of meat to the mother’s identity. The
traceability database is being designed to be capable of expansion and
potentially link into any current or future system of national traceability in
Canada, while also protecting the rights and confidentiality of producers.

“This initiative is a great example of IBM’s industry
knowledge and technology expertise coming together to help solve a strategic
mission for Maple Leaf,” stated Ed Kilroy, President, IBM Canada Ltd. “We are
committed to developing expertise and solutions like this across many key
industries around the world.”
