A Quarter of World’s Pigs are Dying: Expect Food Shortages & Pork Price Spike

Around a quarter of the world’s pigs are expected to die from African swine fever, an expert has claimed. 

Dr. Mark Schipp, president of the World Organization for Animal Health, warned a sharp reduction in the world’s pig population would lead to possible food shortages and high pork prices.

The disease has spread to China, which has half the world’s pigs, in the past year and had inflamed a worldwide crisis, he today told reporters in Sydney.

‘I don’t think the species will be lost, but it’s the biggest threat to the commercial raising of pigs we’ve ever seen,’ he said. 

‘And it’s the biggest threat to any commercial livestock of our generation.’

African swine fever, fatal to hogs but no threat to humans, has wiped out pig herds in many Asian countries. Chinese authorities have destroyed about 1.2 million pigs in an effort to contain the disease there since August 2018.

The price of pork has nearly doubled from a year ago in China, which produces and consumes two-thirds of the world’s pork. 

And China’s efforts to buy pork abroad, as well as smaller outbreaks in other countries, are pushing up global prices.

‘There are some shortages in some countries, and there’s been some substitutions using other sources of protein, which is driving up the prices of other proteins,’ said Schipp.

Progress had been made toward a vaccine, but Schipp, who is also Australia’s chief veterinary officer, said the work was challenging because the virus itself is large and has a complex structure. He said a big step forward was the announcement last week that scientists had unraveled the 3D structure of the virus.

African swine fever is spread by contact among pigs, through contaminated fodder and by ticks. 

It originated in South Africa and appeared in Europe in in the 1960s. A recent reappearance in western Europe came from wild pigs transferred into Belgian forests for hunting purposes.

Its capacity to spread rapidly is shown by its spread from China in the past year, Schipp said. Mongolia, the Korean Peninsula, Southeast Asia and East Timor have had outbreaks as well.

He said the spread reflects the global movement of pork and of people but also the effect of tariffs and trade barriers, which sends those obtaining pork to seek out riskier sources. 

And Schipp said quality control was difficult for products such as skins for sausages, salamis and similar foods.

‘Those casing products move through multiple countries,’ he said. ‘They’re cleaned in one, graded in another, sorted in another, partially treated in another, and finally treated in a fourth of fifth country. They’ve very hard to trace, through so many countries.’

He praised China’s efforts to battle the disease and said the outbreaks would change the way pigs are raised.

‘In China, previously they had a lot of backyard piggeries. They’re seeing this as an opportunity to take a big step forward and move to large scale commercial piggeries,’ Schipp said. 

‘The challenge will be to other countries without the infrastructure or capital reserves to scale up in those ways.’
