I know the Green Book is regularly updated, but the research they refer to is 14 years old. I was looking for something more contemporary as apparently the prevelance of hep A in the UK population has declined in the past 10 years and the stuff I referred to was more recent. However the evidence does seem somewhat lacking and I would be grateful to know what other people do. My staff are not sewage workers, but are occassionally occupationally exposed in a fairly controlled environment, which is why I haven't gone immediately with the Green Book's advice (probably much to my folly!).

A UK study to evaluate this risk showed that frequent occupational exposure to raw sewage was an independent risk factor for hepatitis A infection (Brugha et al., 1998). Immunisation is, therefore, recommended for workers at risk of repeated exposure to raw sewage, who should be identified following a local risk assessment ******************************** Please remove this footer before replying.
