China has banned hog and pork product imports from Mexico and parts of the United States with immediate effect, the government said in a statement posted on official websites on Monday.
The ban was aimed at preventing the outbreak of swine flu from entering China, the agriculture ministry and the General Administration of Quality Supervision, Inspection and Quarantine said in joint statement.
Imports from the US states of Texas, Kansas and California were affected by the move, according to the statement.
The disease cannot be transmitted by eating properly cooked pork but the Philippines has already brought in a similar ban.
No cases of swine flu have been reported in China, which was at the center of the Severe Acute Respiratory Syndrome (SARS) epidemic in 2003, but the government urged citizens to immediately reports any signs.
"At present, there's no swine flu case in China. What we are doing is closely monitoring for human cases and let the public know how to prevent the disease," a health ministry spokesman told AFP today.
