Mosiria raises alarm over unsafe food after fish vendor found cooking near sewer
By David Nthua, February 6, 2026Nairobi County’s Head of Customer Care and Citizens Engagement, Geoffrey Mosiria, has raised the alarm over unsafe food practices after discovering a fish vendor preparing food next to an open sewer.
In a video posted on his Facebook page, Mosiria was seen confronting the vendor, expressing disbelief at the filth surrounding the cooking area.
Mosiria described the scene as deplorable and a serious threat to public health, warning that such unhygienic conditions put unsuspecting customers at risk of food poisoning and other infections.
“Yani hii mnaenda kuuzia watu na mnatengenezea place chafu hivi? Yani hapa watu wanakula sumu tu”, he said in the video, highlighting the dangers of consuming food prepared in such unsanitary conditions.
Public caution
He warned that some traders were prioritising profits over the health and safety of their customers, exposing Nairobi residents to dangerous infections and food poisoning.
According to Mosiria, food prepared or sold in dirty environments can easily transmit serious illnesses that could have long-term effects on families.
Mosiria further urged Kenyans to be extremely cautious about where they buy food or choose to eat, noting that personal vigilance was just as important as enforcement by authorities.
“Your health should always come first”, he said, adding that cheap food could turn out to be very costly when medical bills follow.
Random inspections
The Nairobi County official said his department, working alongside public health officers, would continue conducting inspections across the city to ensure that food vendors comply with hygiene and safety regulations.
He stressed that traders found flouting the law would face firm action, including closure of premises.
Mosiria also called on food vendors to take responsibility and maintain clean environments, saying safe food handling was not optional.
“We cannot allow Kenyans to be poisoned in the name of biashara”, he said.
He encouraged members of the public to report unhygienic food outlets to county authorities, insisting that collective responsibility was key to protecting public health.
