““Farmers in the United States are also permitted to spray the fruit with a synthetic dye called Citrus Red No. 2. The dye is banned in California but may be used by Texas and Florida growers. It is only permitted for fruit that is going to be peeled and eaten or juiced, not for fruit whose rinds will be “processed” into food or drink. Because fruit sold at the grocery store is assumed to be for eating or juicing, it may be sprayed with the dye—and not always labeled as such.””
