Tests by the Californian Department of Public Health revealed that a batch of cherry-flavored bars contained 0.24 parts per million of lead. That exceeds the FDA limit on lead of 0.1 parts per million.

“That potentially could cause health problems, particularly for infants, small children, and pregnant women,” the FDA said in a statement.

Distributor Candy Dynamics of Indianapolis plans to recall all flavors of the sweets ever produced, including sour apple, raspberry, and cherry.

There have been no reports of sickness from the product.

Officials said the tainted feed affected 4,700 farms, primarily pig operations in the Lower Saxony region, the BBC reported Friday.

Last week, over 1,000 German farms were banned from selling egg products after the cancer-causing chemical was found in chicken feed, msnbc.com said.

Officials also ordered more than 8,000 chickens culled Monday in western Germany.

The contamination was traced to a German supplier that accidentally distributed some 3,300 tons of contaminated oils intended for bio-fuels.

Although the dioxin in samples exceeded allowed levels, German officials said the amount didn’t pose a health risk to humans and that the closure of the additional 4,700 farms was a precaution, according to the BBC.

According to UPI, the scare has prompted South Korea to issue a ban on German imports of pork and poultry.

The European Union warned that dioxin had entered the U.K. in processed food products, the BBC said.
