As the province battles the H5N8 strain, chicken products are ever harder to come by.
KFC is one of the hard hit retailers and their popular Zinger and Dunked wings have been temporarily out of stock at a number of outlets.
KFC Africa spokesperson Thanisa Mkhwanasi said the wing shortages in some areas were a direct result of the outbreak of avian influenza.
“KFC South Africa can confirm that KFC restaurants, together with the broader industry, are experiencing a shortage of wings in some areas due to the impact of the outbreak of avian influenza (AI) on bird availability.
"The continued AI outbreaks across the country have intensified the pressure on our supply chain and we will continue to monitor the developments and ensure the impact is minimised."
She said KFC continued to be concerned about the longer term impact the virus may have on national egg banks and the knock on impact on broiler availability.
“We want to reassure our customers that we are working tirelessly with our suppliers to bring supply levels back to normal to meet demand as far as possible.
"Significant discussions are under way between key industry players and government on how best to manage the situation moving forward and KFC is committed to continuing to engage and participate in these efforts.
"In the interim, however, we unfortunately anticipate ad-hoc constrained supply resulting in some restaurants being intermittently out of stock.”
