Questions about an item on this list - or questions about any food item - should be directed to the [Food & Water] section as a new topic. This list will be kept updated as unsafe food items are brought to our attention.

While it is true that crabs are scavengers with a wide repertoire of foods they can eat, there
are many plants and foods that just should not be fed to a crab. The foods on this list are to
be avoided. Some are toxic, some are insect repellents or used as insecticides, and some the crabs
just won't go near, such as lemon -- lemon won't hurt them, but they certainly won't eat it.
This list, like the Edible List, will be updated regularly, so be sure to check back often.
