Toxic sukuma wiki on sale in Nairobi: study

What you need to know:

  • Researchers from the University of Nairobi have sampled sukuma wiki grown in Athi River, Ngong and Wangige and that sold in Kawangware, Kangemi and Githurai markets and concluded it is toxic.
  • The study, led by Carl Johan Lagerkvist of the Swedish University of Agricultural Sciences and published in the current issue of the East African Medical Journal, blames poor cultivation and handling practices for the unhygienic state of the vegetables.
  • The researchers tested the kales for coliforms, a broad class of bacteria found in the environment including in human and animal waste.

Much of the sukuma wiki (kales) on sale in Nairobi is highly contaminated and poses a serious health risk to consumers.
