It is illegal to bring certain fruits from Hawaii back to the mainland. Fruits that are prohibited from crossing the state’s borders are pineapple, pure papaya, all citrus, coconuts, banana, guava, mango, lychee, taro and Breadfruit.
These restrictions are put in place to prevent the spread of invasive species and the potential spread of disease and harmful insects, which could disrupt the Hawaiian ecosystem. In addition, Hawaii also has restrictions on plant material, so it is also important to check with the state’s Department of Agriculture before attempting to bring any kind of greenery back with you.
