Nutrition label changes that were intended to make information on them clearer and easier to understand have been postponed, the Food and Drug Administration said on Tuesday.

The deadline had been late July 2018. The postponement was a response to “numerous stakeholders” requesting more time, the regulator said, though it did not say what the new deadline would be.

Issues included, among other things, “the need for upgrades to labeling software, getting nutrition information from suppliers, the number of products that would need new labels, and a limited time for the reformulation of products,” said FDA spokesperson Deborah Kotz. “Developing these types of extensions can take some time, so we want to be as transparent as possible throughout the process.”

The news is only the latest such move from the FDA, which delayed a calorie labeling rule for national restaurant chains by a year, until May 2018. The FDA’s new commissioner, Dr. Scott Gottlieb, was appointed by President Donald Trump this year.

The planned nutrition label changes include a more prominent display of calories, more realistic serving sizes, labeling the amount of added sugars and a column showing total calories in the whole package.

Industry groups wrote to Health and Human Services Secretary Tom Price in March asking that the deadline be extended to May 2021, according to a letter made public by the nonprofit health watchdog group Center for Science in the Public Interest.

“The current compliance deadline does not sufficiently account for the time, resources and complexity involved in label changes of this magnitude,” the groups, which included the Grocery Manufacturers Association and the North American Meat Institute, said.

But some companies may already be on track to meet the previous deadline. For example, KIND Healthy Snacks said last year that it was on track to revise labels by July 2018.

CSPI criticized the delay. “As with its delay of menu labeling, the FDA will end up denying consumers critical information they need to make healthy food choices in a timely manner and will throw the food industry into disarray,” said Jim O’Hara, CSPI’s director of health promotion policy. “The ability of the Trump administration to repeat its mistakes is breathtaking.”

More information about the extension will be released “at a later time,” the FDA said.
