U.S. marshals seized more than 80 cases of "probiotic" products Tuesday from UAS Laboratories in Eden Prairie, alleging that the firm flouted previous warnings from the U.S. Food and Drug Administration and made claims of unproven medical benefits.
The company manufactures and markets probiotic products, which deliver what some call "good" bacteria to the gut. Such microorganisms are believed to be healthful for their host.
UAS President Sita K. Dash denied mislabeling his products and said Tuesday that the firm is working with the FDA to resolve the dispute.
"The first thing we want our customers to know is that our products are safe and effective and they need not worry about the probiotics they are taking. That is not at issue with the FDA," the company said in a statement.
"What is at issue with FDA are statements made on our website that FDA believes expand our labeling and make 'drug-like' claims for our probiotics. So like nutritional supplements, we cannot make claims beyond describing general health benefits even though the medical and scientific literature may be suggestive of certain more specific health benefits."
Dash founded UAS in 1979 after spending six years with the South Dakota Department of Agriculture's food and drug division, where he rose to become its director.
The FDA warned Dash in May 2005 that an inspection had found "serious" labeling violations for a number of UAS probiotics. The company had claimed that some could inhibit ulcers, protect against E. coli and salmonella infections, reduce vaginal and yeast infections, promote the body's cancer-fighting activities, reduce cholesterol and help prevent rotoviral diarrhea.
Websites ranging from the Mayo Clinic to the World Health Organization and Harvard and Tufts universities have cited research indicating similar findings about certain probiotic products. But linking such claims to specific products triggers regulatory oversight, said Siobahn DeLancey, an FDA spokeswoman.
