The University of Zimbabwe says it is still carrying out investigations and laboratory tests to a number of fish samples from Lake Chivero to ascertain if it is contaminated with the typhoid bacteria.
This follows some media reports that warned Harare residents against consuming fish from Lake Chivero saying they have typhoid coming from human faecal contamination.
The University of Zimbabwe says more investigations and laboratory tests need to be done before concluding that fish from Lake Chivero are contaminated with typhoid bacteria.
In an interview, University of Zimbabwe Researcher, Professor Mafongoya Paramu said scientifically it does not make sense to believe that fish from the lake contain typhoid bacteria considering that fish feed on a number of materials and that faecal material is organic and can be cleared in the process of digestion.
â€œThe bulk of the fish that have the typhoid bacteria are contaminated due to poor handling by vendors,â€ said Professor Paramu.
Last week, Environment and Natural Resources Management Minister Francis Nhema challenged different stakeholders to come together and carry out appropriate research to correctly inform the nation.
â€œStakeholders must find a way of ensuring that fishing activities at Chivero or even Darwendale are controlled so that vendors do not end up with too much fish than can be consumed within a limited period to avoid contamination,â€ Minister Nhema said.
Harare City Health department last week said laboratory tests conducted by government analysts and the Standard Association of Zimbabwe did not conclude that fish from Lake Chivero is contaminated with the typhoid bacteria.
Poor handling of food stuffs, especially by vendors has been cited as the main cause of the typhoid outbreak in Harare.
More than 2 800 people have been treated for the bacterial disease with up to 50 new cases being reported every day.
