Many women in Juba complain that traders are mixing up dry okra known as Weka with mattress, yeast and other chemicals.
They say the food sometimes takes too long to be ready and sometimes causes illness to consumers, Radio Bakhita reports.
The complaints flared up during media visit of Juba town market.
Meanwhile, one woman who sells okra dismisses the complaints, saying she does not sell contaminated food items.
Bakhita Radio is yet to follow authorities over the matter.
