The exclusive contract to supply South Africa with a foot-and-mouth disease vaccine has been allegedly terminated by the overseas manufacturer.
This affects the local company that was set to import millions of doses to help control outbreaks in livestock.
The company says it did not withdraw its application and that the decision came after talks involving government officials.
Authorities say their main priority is to ensure a stable and reliable supply of vaccines for farmers.
Meanwhile, agricultural groups are urging urgent action as foot-and-mouth disease continues to threaten food security and the farming sector.
