In June 2015, the FDA issued a final statement. It says there is no agreement by scientists that artificial trans fatty acids are safe for any use in human food. Trans fat must be taken out of all food production within three years (by June 2018). The FDA says the ban will cost the food industry $6.2 billion over 20 years. The food industry must use new formulas and recipes using ingredients without trans fat. The benefits will be about $140 billion over 20 years. This will be mostly from lower health care costs. Food companies can issue requests to the FDA for permission to use partially hydrogenated oils. The companies must prove the oils' use is safe.
