Mishandling potting mix can cause the potentially fatal Legionnaires' disease. A health warning has been issued for gardeners after a Dunedin man died from Legionnaires' disease less than a week after handling potting mix. A University of Otago study found potting mix labels failed to adequately warn many gardeners about the risks of Legionnaires' disease. For her master of science in psychology, Catherine Thomas investigated labels on bags of potting mix and on bleach. ALICE FALLOON/STUFF Catherine Thomas' University of Otago Master of Science degree studied ways of improving warning labels on bags of potting mix.
