International Paper, Duda Farm Fresh Foods and H.E. Butt Co. have donated a total of $200,000 to the Center for Produce Safety.

Memphis, Tenn.-based International Paper is contributing $100,000 to support the University of California-Davis center’s competitive research grant programs, according to a news release. Oviedo, Fla.-based Duda Farm Fresh Foods and San Antonio-based H-E-B each pledged $50,000.

The Center for Produce Safety has paid $9 million for 59 one- and two-year research projects over the past three years. Another $3 million is available this year; the latest proposals are under review.

The organization’s third annual Produce Research Symposium is set for June 27 at the Mondavi Center in Davis.

International Paper supplies corrugated packaging to the fresh produce industry.

“Supporting this valuable research is just one more way that International Paper can add value to our customers by helping to ensure the delivery of safe, fresh, high-quality produce to consumers,” Peter Heist, area vice president, said in the release.

“We believe the scientific research funded by CPS is crucial to enhance food safety and we are thrilled to make a contribution toward this goal,” Sam Duda, vice president of Duda Farm Fresh Foods, said in the release.

“These three companies representing retail, production and industry suppliers demonstrate that food safety is taken seriously by the fresh produce industry,” Stephen Patricio, chairman of the center’s advisory board, said in the release.
