Be careful of fruit and produce bought at farmer’s markets or the open air markets in third world countries. Cabbages, lettuce and other leafy items are often home to larvae that can and will hatch at some point, so make sure you inspect and wash the produce before storing it aboard. Bananas and other fruit, particularly if bought on the stalk, can deliver to your boat such fruit gourmets as scorpions and tarantulas hidden deep within the bunches.
