Researchers at the University of Guelph in Ontario, Canada, are starting new projects funded by the Canadian Poultry Research Council and the federal government. The projects focus on areas such as avian influenza, embryo and chick activity, alternative antibiotics, feed additives, and egg disinfection. Other areas of study include the impact of climate change on poultry gut health and the potential uses of compounds found in litter. Food science researcher Dr Keith Warriner will also look into using antimicrobial gas-phase hydroxyl radicals for egg and hatchery surface cleaning.
