When the FDA announced in January, earlier than President Joe Biden’s time period ended, that it could ban a dye known as purple dye No. 3 in meals and ingested medication, the federal company cited only one 1987 research on rats to help its motion.
The industry-funded study, based mostly on knowledge from two prior research, was led by a Virginia toxicologist who mentioned then — and nonetheless believes at present, many years after considerations first arose that the chemical may very well be carcinogenic — that his analysis discovered the petroleum-derived meals coloring doesn’t trigger most cancers in people.
“If I thought there was a problem, I would have stated it in the paper,” Joseph Borzelleca, 94, a professor emeritus of pharmacology and toxicology at Virginia Commonwealth University, instructed KFF Health News after the FDA’s announcement. “I have no problem with my family — my kids and grandkids — consuming Red 3. I stand by the conclusions in my paper that this is not a problem for humans.”
Soon after Borzelleca’s paper was revealed in a scientific journal, Food and Chemical Toxicology, the FDA examined the information his staff had collected and reached its personal conclusion: that the dye prompted most cancers in male lab rats. In 1990, the FDA cited the research in banning Red 3 in cosmetics.
In 1992, the FDA mentioned it wished to revoke approval of Red 3 in meals and medicines. But the company didn’t act on the time, citing an absence of sources.
More than 30 years later, after a renewed push by client advocates, the Biden administration introduced the ban in its final days in energy. The transfer got here simply weeks earlier than the Senate confirmed Robert F. Kennedy Jr., President Donald Trump’s nominee to move the Department of Health and Human Services, which oversees the FDA.
Kennedy has been a vocal critic of meals components, together with Red 3. On March 10 he met with high meals business executives and instructed them in the event that they don’t get rid of synthetic meals dyes from their merchandise, the federal authorities will pressure them to take action, Food Fix reported.
Consumer advocacy teams cheered the Red 3 ban, even because the FDA mentioned there isn’t any proof that the dye is harmful to folks. “Importantly, the way that FD&C Red No. 3 causes cancer in male rats does not occur in humans,” Jim Jones, FDA deputy commissioner for human meals, mentioned in a press release.
Jones resigned from FDA in February, criticizing Trump administration cuts that he mentioned hobbled his workplace.
The FDA didn’t reply to a request for remark, however Marty Makary, Trump’s nominee to guide the company, mentioned at his Senate affirmation listening to on March 6 that he’s involved about whether or not meals components corresponding to Red 3 hurt kids.
“It did not make sense that red dye No. 3 was banned in cosmetics but allowed in the food supply,” Makary instructed Sen. Tommy Tuberville, who questioned why the FDA ban doesn’t take impact till 2027.

“We want to kill people for two more years?” the Alabama Republican mentioned. “I would hope that you would, if you’re confirmed, you’d go in and look at it very quickly and say, ‘Why do we want to put our people in harm’s way?’”
The International Association of Color Manufacturers says Red 3 is protected within the tiny ranges sometimes consumed by people. The dye was permitted to be used in meals within the U.S. in 1907, and at present it’s an ingredient in 1000’s of merchandise together with cereals, sweet, drinks, and cake toppings.
Thomas Galligan, principal scientist for meals components and dietary supplements on the Center for Science within the Public Interest, which petitioned the FDA for a ban, mentioned {that a} federal regulation often known as the Delaney Clause prohibits any ingredient that causes most cancers in animals from being included in meals. (The writer of KFF Health News, David Rousseau, is on the CSPI board.)
“At the end of the day, this is an unnecessary additive,” he mentioned. “It’s a marketing tool for the industry to make foods look more appealing so consumers will buy them. But federal law is clear: No amount of cancer risk is acceptable in foods.”
Galligan mentioned he was not stunned Borzelleca’s opinion on Red 3 had not modified or that the meals dye business has performed down the danger.
In October 2023, California turned the primary state to ban Red 3 in meals beginning in 2027, superseding the FDA’s earlier rule permitting small quantities in meals as a shade additive. The state legislature acted after a state analysis concluded the dye might trigger hyperactivity in kids.
The European Union, Australia, and Japan are among the many areas that already ban the chemical in meals. The EU’s ban additionally cites hyperactivity in kids. The EU requires meals makers to incorporate a warning that meals dyes which are nonetheless allowed might “have an adverse effect on activity and attention in children.”
The IACM factors to analysis by scientific committees operated by the World Health Organization, together with a 2018 review that affirmed the security of Red 3 in meals.
Some meals producers have already reformulated merchandise to take away Red 3. In its place they use beet juice; carmine, a dye comprised of bugs; or pigments from meals corresponding to purple candy potato, radish, and purple cabbage.
It isn’t clear how the FDA decided that Red 3 may cause most cancers in male rats. Borzelleca’s paper mentioned some rats that have been fed Red 3 developed polyps of their thyroid gland however doesn’t point out most cancers.
Borzelleca, whose research was funded by the IACM, then often known as the Certified Color Manufacturers Association, mentioned he was surprised the FDA banned the dye and used his analysis to again the transfer.
“I am surprised all this time has gone by and it’s been safe for human use, and now it’s being pulled from the market due to concerns not supported by the data,” Borzelleca mentioned. “Our study did not find this was a carcinogen.”
His research was a response to the FDA’s requirement within the Eighties for extra long-term feeding research in rats and mice as a situation for the continued provisional approval of a number of shade components, together with Red 3.
Over many years, Borzelleca revealed dozens of analysis papers on the toxicology of meals components, pesticides, and water contaminants. He additionally served on advisory boards for the tobacco business and represented cigarette maker R.J. Reynolds in negotiations with the Department of Health and Human Services about cigarette components, in response to a 1984 company memo. Borzelleca is a former president of the Society of Toxicology and consulted for the National Academy of Sciences and the World Health Organization.
The commonwealth of Virginia gave him a lifetime achievement award in 2001 for his work serving to assess risks in meals, medication, and pesticides.
