Maseno market and its environs are courting germ-related diseases.
Public health officer Peter Ogwel said there are no public toilets at the market.
This has led to open defecation posing a health hazard to the local community and Maseno University students.
"We asked the council (City Council of Kisumu) in May to put up the facilities but to date they are yet to build the toilets," Ogwel told the Star.
He said some students of Maseno University who reside in private hostels were likely to be affected incase of an outbreak of diarrheal diseases.
"Some of them take their meals at the local hotels and kiosks," he said.
Maseno University public relations officer George Ojwondo said: "It is affecting residents around and not students since our institution has enough facilities."
Efforts to reach the council's chairman Fredrick Onyango and clerk Ben Opiyo were futile.
