Sanitary inspectors—known in Yoruba as Wole-wole, literally “those who enter homes”—were among the most visible and powerful public health officials in colonial and early post-colonial Nigeria. Active from the early 1900s through the 1970s and beyond, they became symbols of both the state’s commitment to hygiene and the tensions that surrounded public health enforcement.
Early Origins and Role
The office of the sanitary inspector was established under British colonial rule in the early 20th century to curb the spread of infectious diseases in rapidly growing towns. Working alongside colonial medical officers, sanitary attendants (as they were first called) inspected homes, markets, schools, and public spaces to ensure that residents complied with sanitation laws. They monitored water storage, enforced proper waste disposal, and ensured that households maintained clean surroundings.
Authority and Public Perception
These inspectors wielded broad legal powers that allowed them to enter private homes without notice. They could confiscate items considered unhygienic and, when necessary, fine or prosecute offenders in colonial courts. Their surprise visits and strict enforcement quickly gave them a fearsome reputation. In popular memory, later generations even compared their authority to that of the much-feared Special Anti-Robbery Squad (SARS), underscoring how intimidating their unannounced inspections could be.
Corruption and Controversies
With such extensive authority came opportunities for abuse. Records from the 1930s and 1940s in Western Nigeria describe cases of inspectors demanding bribes to overlook sanitation breaches. While these practices tarnished their image, sanitary inspectors nevertheless remained central to the control of epidemics and the promotion of urban hygiene.
Legacy and Impact
Despite the controversies, the Wole-wole were instrumental in reducing outbreaks of cholera, smallpox, malaria, and other infectious diseases. Their activities helped shape the foundation of Nigeria’s modern public health system and directly influenced the creation of today’s Environmental Health Officers, who continue to enforce sanitation standards.
The story of the Wole-wole captures the complexities of colonial public health: an ambitious campaign for cleaner, healthier cities that depended on a cadre of inspectors who inspired both respect and fear.
