New research indicates big savings possible for retailers

BRAMPTON, Ontario — July 18, 2016 — New research by the University of Bologna indicates that corrugated trays keep fruit fresher and safer than reusable plastic containers (RPCs). Researchers examining both shipping options found corrugated trays added up to three days shelf life and significantly reduced contamination from pathogenic and spoilage microorganisms.

Two press releases outline the findings. Both are available on the Canadian Corrugated and Containerboard’s website: Please visit the “In The News / Issues” section.

The chief finding was that corrugated trays ensured higher-quality packed fruits with reduced microbial cross-contamination and longer shelf life. Lower bacterial contamination decreased the risk of foodborne illnesses and increased the fruit’s freshness, scent, appearance and taste.

The European research was led by Professor Rosalba Lanciotti at the University of Bologna’s Department of Agricultural and Food Sciences. Her team focused on determining how differences in packaging materials can influence cross-contamination. They packed peaches in deliberately contaminated packaging of both types and measured transfer of the microorganisms.

“Food contamination is a serious concern for growers, shippers and retailers who work diligently to ensure food is shipped in clean containers free of bacteria,” says David Andrews, Executive Director, Canadian Corrugated and Containerboard Association. “They also wrestle with sustainability and cost concerns. The role of packaging is critical in all these areas. It’s why our industry is committed to providing food safe packaging that is also environmentally sustainable and cost effective. The University of Bologna’s work has now added a new dimension and more information for our Canadian stakeholders.”

For the benefit of Canadian growers, packers and retailers, the corrugated industry has sponsored several independent studies evaluating food safety in respect to corrugated containers and reusable plastic crates over the past three years. In 2013 and 2014 Dr. Warriner (University of Guelph) assessed the microbiological standard of RPCs used in different fresh produce packing stations. He found that RPCs used to ship fruits and vegetables in Ontario and Quebec had alarming levels of sanitization and significant risk for food contamination. Information on Dr. Warriner’s studies, as well as factually researched reports undertaken by two respected US based academics, can also be found on the CCCA website’s “In The News / Issues” section at
