Seroprevalence of Hepatitis B among Food Handlers in Kozhikode

Hepatitis B remains a significant public health concern, particularly among occupational groups at risk of exposure. Food handlers are a crucial population to consider when assessing hepatitis B virus (HBV) seroprevalence in public health surveillance due to their frequent interaction with the community.

To assess the HBV seroprevalence and associated factors among food handlers in Kozhikode.

A community-based cross-sectional study was conducted using multistage sampling. Food handlers from various food establishments in three blocks of Kozhikode district were included. A total of 1,145 participants were recruited. Data were collected by interview using a pre-tested semi-structured questionnaire. Results are expressed as proportions and means with standard deviations.

Out of 1,145 participants, the majority were males, 77% of the participants were from Kerala. Injury was present in 2.2% of participants. HBV seroprevalence was 0.6% among food handlers. All positive participants were aged 31-45 years, 85.7% were male, and 43% were involved in cooking. However, all were asymptomatic and unaware of the infection.

With a 0.6% HBV seroprevalence among food handlers, the public health implications are significant. A comprehensive health and safety package tailored for food handlers is essential to mitigate risks.
