  1. Use gloves to handle amphibians

    A small, replicated study in a laboratory (Sobotka & Rahwan 1994) found that latex, but not vinyl gloves caused death in African clawed frog Xenopus laevis tadpoles. All tadpoles exposed to unrinsed and rinsed latex gloves died within 24 hours, most within two hours. None of the tadpoles exposed to vinyl gloves showed adverse effects. Four of 12 tadpoles in tanks cleaned with latex gloves died within four hours of exposure. Between 10 and 20 tadpoles were placed in each of three 700 ml beakers containing water at 20°C. One of the following gloves was partially immersed for 24 hours in each beaker: unrinsed latex (powder-free); rinsed latex; or rinsed vinyl gloves. Rinsing was done in deionized distilled water to remove any powder.
