fhrs:rating has been used (But should not be used!) to give the actual hygiene rating values from the UK Food Hygiene Rating System external dataset.
As part of the discussion leading up to the UK 2016 Q4 Project: Food Hygiene Ratings, it was decided that transient data such as this should not be included as tags in OpenStreetMap for maintenance reasons, and also the fact that all the data can be found from the fhrs:id=* link.
The hygiene rating values are a score from 0 to 5. It's the primary purpose of the FHRS database, but not the only useful data in there. We're using FHRS data primarily cross-checking the existence of food establishments (find ones which have not been mapped yet, or ones which have closed). We're also importing address fields, but not these actual hygiene ratings.
