The Blue Plate Mayonnaise Factory is now known as the Blue Plate Artist Lofts. Blue Plate was one of the primary mayonnaise manufacturers in the country. Blue Plate mayonnaise was originally produced in the city of Gretna, Louisiana, until production was moved to 1315 S Jefferson Davis Parkway in the small Gert Town neighborhood in 1941. Some people believe that the production of the mayonnaise came to a halt because of Hurricane Katrina , but the factory stopped producing Blue Plate mayonnaise in 2000. Reily Foods Company, which owned the brand, found a more up-to-date factory in Tennessee. Although the building suffered some damage in the hurricane, and was shut down, its historic architecture has been replenished.
