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!).

The Green Book chapter on Hepatitis A updated in 2009 is quuitre clear on this:

- sewage workers:
raw, untreated sewage is frequently contaminated with hepatitis A. 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
