  1. Use gloves to handle amphibians

    A replicated, controlled study in the laboratory and in the field in Australia (Cashins, Alford & Skerrati 2008) found that unrinsed latex or nitrile gloves caused death of green-eyed tree frog Litoria genimaculata and cane toad Bufo marinus tadpoles and unrinsed vinyl gloves death of waterfall frogs Litoria nannotis. Direct or indirect contact with unrinsed latex gloves caused 72% mortality of green-eyed tree frog tadpoles (n = 36). Unrinsed latex or nitrile gloves caused 10–100% mortality of non-native cane toad tadpoles (n = 10). Rapid, localized tissue damage was observed at the point of contact. In the laboratory, no adverse effects were seen 24 hours after handling with unrinsed vinyl gloves in green-eyed tree frogs (n = 23), cane toads (n = 20) or waterfall frogs Litoria nannotis (n = 32). However, in the field 40% of waterfall frogs handled with unrinsed gloves died within one hour. The remainder and those handled with rinsed vinyl gloves showed no effects. Cane toad tadpoles handled with unrinsed vinyl gloves or bare hands (n = 10–20) showed no adverse effects. In the laboratory, tadpoles were handled for 30–90 seconds with unrinsed latex or vinyl gloves, and nitrile or no gloves for cane toads. In the field, 30 waterfall frog tadpoles were handled with unrinsed or rinsed vinyl gloves or bare hands.
