The FAO and OIE 2020 annual report on the Global Control of African Swine Fever describes the disease as a major global crisis affecting pig industries and rural communities. It notes continued spread in 2020, disruption from COVID-19 to field activities, and that some countries eliminated the disease.
Ongoing ASF spread keeps pork supply constrained and sustains demand for feed ingredients from hog producers, though this report is a general programme update with no immediate price shock.
After 69 past neutral disease events, Lean Hogs moved a median -0.2% over 5 sessions (48% higher; middle half -1.4% to +1.5%), and -1.6% over 20.
