Federal agents seized items from the Hmong Village in St. Paul on Wednesday as part of an investigation into medications sold at the market.
The market, near Lake Phalen on the city's east side, features individual vendors selling everything from dresses to food.
But investigators say they've spent months looking into the distribution of certain medications, including drugs without prescriptions, medications that were mislabeled and products containing mercury.
St. Paul police, which helped execute the search warrant, say the U.S. Food and Drug Administration received reports of illnesses stemming from the products sold at the market. No arrests were made, but several vendors were cited.
Other agencies involved in the search included the Ramsey County Sheriff's Office, the U.S. Drug Enforcement Administration, the United States Postal Inspection Service and the Minnesota Board of Pharmacy.
The investigation is ongoing.
About five years ago, several individuals at another business, the Hmongtown Marketplace, near the state Capitol, were charged after community members fell sick from products purchased there.
