The authorities have banned the import of fowl, fowl carcasses as well as eggs meant for breeding purposes from countries hit by avian influenza.
Bird flu has recently been detected in India, Bangladesh, Vietnam, Israel, Cambodia, Burma, Nepal and Bhutan.
The World Organisation for Animal Health also announced that 18 people had come down with bird flu in Indonesia, Egypt and Vietnam this year. Of the 18, five have succumbed to the disease.
"We are closely monitoring vehicles and people at border checkpoints," Apai Suttisang said yesterday in his capacity as head of the Bureau of Disease Control and Veterinary Services.
According to him, anyone smuggling fowls from the affected countries will find the birds seized and exterminated.
Apai added that all cars, motorcycles and trolleys coming from the avianflu hit countries were being sprayed with disinfectant as a measure to prevent the outbreak of the disease in Thailand.
Livestock Development Department director general Preecha Somboonprasert said for the past 490 days no bird flu has been detected in Thailand.
"We have already informed all provincial governors, especially those in border provinces, to be on alert. If fowls die en masse in a suspicious manner, inform us immediately," he said.
Apai also called on people to alert livestock officials if they found anyone smuggling fowl.
