CGC study shows drop in cadmium levels in durum exports

Nov 08, 2022

A Canadian Grain Commission study confirms a decrease in cadmium concentration in Canadian durum exports.

Cadmium is a naturally occurring heavy metal that, because of its presence in soil, can be a food contaminant.

Dr. Sheryl Tittlemier with the CGC says high cadmium levels are a concern as they can lead to various negative health effects if consumers have large exposures to it.

For this study, Dr. Tittlemier and her team monitored export shipments of Canadian durum wheat for cadmium concentrations from 1992 to 2020.

The survey found that cadmium concentrations have consistently declined since the establishment of the durum breeding program in 1991 that prioritized low cadmium accumulation, and the addition of a low cadmium accumulation variety registration requirement in 2004.

Video: Finding a Balance of Innovation and Regulation - Dr. Peter Facchini

Regulations help markets and industry exist on level playing fields, keeping consumers safe and innovation from going too far. However, incredibly strict regulations can stunt innovation and cause entire industries to wither away. Dr. Peter James Facchini brings his perspective on how existing regulations have slowed the advancement of medical developments within Canada. Given the international concern of opium poppy’s illicit potential, Health Canada must abide by this global policy. But with modern technology pushing the development of many pharmaceuticals to being grown via fermentation, is it time to reconsider the rules?

Dr. Peter James Facchini leads research into the metabolic biochemistry in opium poppy at the University of Calgary. For more than 30 years, his work has contributed to the increased availability of benzylisoquinoline alkaloid biosynthetic genes to assist in the creation of morphine for pharmaceutical use. Dr. Facchini completed his B.Sc. and Ph.D. in Biological Sciences at the University of Toronto before completing Postdoctoral Fellowships in Biochemistry at the University of Kentucky in 1992 & Université de Montréal in 1995.
