The Philippines on Monday reported its first cases of African swine fever, becoming the latest country hit by the disease that has killed pigs from Slovakia to China, pushing up pork prices worldwide.
The virus is not harmful to humans but causes haemorrhagic fever in pigs that almost always ends in death.
There is no antidote or vaccine and the only known method to prevent the disease from spreading is a mass cull of affected livestock.
Infected pigs were found in two towns near the Philippine capital Manila and authorities have culled more than 7,000 pigs within a one-kilometre (0.6-mile) radius, said Agriculture Secretary William Dar.
He said the nation was not facing an epidemic and urged Filipinos to continue eating pork, which is a critical market and accounts for 60% of meat consumption in the Philippines.
The Asian country is the world’s 8th biggest pork producer by volume and its swine industry is estimated at 260 billion pesos ($5 billion), according to the agriculture department.
Dar said 14 of 20 samples sent to a UK laboratory tested positive for African swine fever, but it will take another week to confirm how virulent the strain is.
