Avocados grown in California may not be truly vegan, due to the manner in which they are pollinated. An insufficiency of honey bees means that farmers use migratory beekeeping, in which hives are temporary placed in avocado fields. When the season is over, bees are left without natural food sources and are fed by their keepers on sugar syrup or pollen patties, which are less nutritious than their wild diet. Entire hives can also collapse due to disease. Other fruit and vegetables, including apples, blueberries, squash and cucumber, may also be produced using this method of beekeeping.
