It is time to reassess whether the EU’s blanket ban on the use of food waste as feed is the right thing for the pig industry.

A new study shows that if the European Union lifted the pigswill ban imposed following 2001’s foot-and-mouth disease epidemic, and harnessed technologies developed in East Asian countries for ‘heat-treating’ our food waste to safely turn it into pig feed, around 1.8 million hectares of land could be saved from being stripped for grain and soybean-based pig feed production – including over quarter of a million hectares of Brazilian forest and savannah.
While swill-feeding was banned across the EU in 2002 following the foot-and-mouth outbreak – triggered by a UK farmer illegally feeding uncooked food waste to pigs – other countries, such as Japan, responded by creating a highly regulated system for safely recycling heat-treated food waste as animal feed.
Researchers describe the EU ban as a “knee-jerk reaction” that no longer makes sense when East Asian countries have demonstrated that food waste can be safely recycled. The models in the latest study show that pigswill reintroduction would not only decrease the amount of land the EU pork industry requires by 21.5%, but also cut in half the ever-increasing feed costs faced by European pig farmers.
Researchers describe swill as a feed which is commonly used in other parts of the world, one that could save a huge amount of global resources, and provide an environmentally sound recycling solution to the estimated 102.5 million tonnes of food wasted in the EU each year. Over 35% of food waste is now recycled into animal feed in Japan, where swill-fed “Eco-pork” is marketed as a premium product.
“Following the foot-and-mouth disease outbreak, different countries looked at the same situation, the same evidence, and came to opposite conclusions for policy,” said Erasmus zu Ermgassen from the University of Cambridge’s Department of Zoology, who led the study, published in the journal Food Policy. “In many countries in East Asia we have a working model for the safe use of food waste as pig feed. It is a highly regulated and closely monitored system that recycles food waste and produces low-cost pig feed with a low environmental impact.”
