Food fraud expert warns of certain garlic powders could contain inferior ingredients

One of the world's foremost experts on food fraud is warning about the possibility that garlic powder on store shelves, including those in Canada, may contain inferior ingredients.

Christopher Elliott of the Institute for Global Food Security at Queen's University Belfast says garlic sales around the world this year are on pace with sales last year, despite a cold spell that wiped out vast tracts of garlic crops in China.

Elliott and other researchers are investigating garlic supply chains to determine whether garlic powder has been diluted with other products, such as talcum or chalk.

Last year, Elliott published a study that showed about a quarter of oregano sold in the UK. and Ireland contained other products, including olive and myrtle leaves.
