China and a string of other countries are banning pork and other raw meat products from some U.S. states in the wake of the swine flu outbreak, which so far has not been detected in any pigs nor can be spread from eating pork.

After taking hits on product safety for everything from tainted toys to tainted milk, China wasted no time banning U.S. pork imports in the wake of the swine flu outbreak.

China and a string of other countries have moved to ban pork and other meat products from some U.S. states over the past week. The trend on Tuesday drew a rebuke from U.S. officials, who are warning trading partners that such embargoes could trigger "serious trading disruptions."

The Centers for Disease Control and Prevention and other health organizations insist that the strain cannot be spread by food and that properly cooked pork is safe.

But according to the Chinese news agency Xinhua, the Chinese government ordered all pork products from Mexico, Texas, Kansas and California destroyed or returned to the suppliers.

"(The) restrictions on U.S. pork or pork products or any meat products from the United States resulting from the recent outbreak do not appear to be based on scientific evidence and may result in serious trade disruptions without cause," U.S. Trade Representative Ron Kirk said in a statement Tuesday.

The list of countries imposing some style of U.S. pork ban is fluid but expanding.

Jim Herlihy, with the U.S. Meat Export Federation, told FOXNews.com that such bans have so far been implemented in China, Russia, Honduras, El Salvador, Lebanon, Ukraine and Thailand.

Kazakhstan, Philippines and the United Arab Emirates are also banning U.S. pork, according to Kirk's office.

Herlihy said Russia has only banned meat from certain U.S. states and Mexico that has not been "heat-treated." The country will take cooked pork, but countries like China are turning away any pork products from flagged U.S. states.

Herlihy said the bans should be reversed but warned that the number could continue to grow.

"Our fear is seeing people or seeing countries take a non-scientific approach to this and responding emotionally," he said, warning that those countries were stirring "unnecessary fear."

U.S. Agriculture Secretary Tom Vilsack said in a statement "there is no evidence at this time that swine has been infected with this virus." He said consuming pork is "of no risk" to consumers.

According to the U.S. Meat Export Federation, the number of countries banning U.S. pork make up about 8 to 10 percent of America's pork export partners.

While Mexico has seen more than 150 suspected flu-related fatalities, no such deaths have been reported in the United States.
