Chocolate-flavored body "spreads" sold in British sex shops are said to be tainted with the same poisonous chemical blamed for the deadly Chinese milk crisis, Reuters reported Monday.

The British Food Standards Agency (FSA) said the industrial chemical melamine has been found in Chinese-made "I Love You" sets, sold at Ann Summers sex shops.

The chemical was found in chocolate and strawberry "body pens" and chocolate-flavored body spreads.

"This is a first. We've never had to put out an alert before on 'willy spread' — chocolate-flavored or otherwise," the FSA said on its Web site.

The health risk from the affected products is believed to be low, according to the report.

The milk scandal, which has killed four infants and sickened thousands more, is one of the worst tainted food crises in China in years.

It has exposed shoddy practices in the booming dairy industry and raised questions about when the government first knew dairy products were contaminated with melamine, a chemical used in making plastics and fertilizers. Unscrupulous suppliers are suspected of adding it to watered-down milk to mask the resulting protein deficiency in quality tests.

In recent weeks, Chinese-made products, including candy, sold in the U.S. have been found to be contaminated with melamine. The U.S. Food and Drug Administration has said that melamine is not harmful if consumed in low doses.
