Sheep dip sufferers support group update

19 Apr

Following the 2015 post on this website, comes news from Warrington farmer Tom Rigby, co-ordinator of the Sheep Dip Sufferers’ Group, who sent a press release reporting that HSE had released details of their 1992 Sheep Dipping Survey which may be seen on their website – the report here and appendix here.

Readers new to this subject may first wish to read the full history on the group’s website.

HSE identified 700 farmers in 16 different regions of GB (385 in England, 155 in Scotland and 160 in Wales) broadly typical of the whole and 696 surveys were completed. There were 160 occasions described where some form of ill-health occurred after dipping, only three of which had been reported to MAFF/VMD. If this was representative of UK’s 90,400 sheep flocks it suggests over 20,000 cases nationwide.

HSE’S Epidemiology and Medical Statistics Unit suggested a better way of expressing these findings were as “a crude incident rate of 8.9 self-reported illness episodes per 1000 dippers per annum”. This suggests a total of over 33,000 for MAFF’s compulsory dipping years 1976-92. Mr Rigby comments that trying to calculate incident rate this way almost certainly gives an under-estimate due to what is known as the ‘healthy worker’ effect as it ignores fatalities and those too ill to continue working (similar to trying to estimate road traffic incidents over 10 years just by interviewing current drivers).

Cumulative exposure

Tom Rigby says: “Whatever the precise figure it does seem by 1992 HSE were aware of the devastating effects dipping was having on the health of sheep farmers. We believe this is the reason MAFF ended compulsory dipping in June that year (something they have always denied) and we request disclosure of correspondence between HSE and MAFF in the weeks prior to that decision being taken”.

The initial results of this HSE study were published as a news release dated 20th July 1993 with the title “HSE SURVEY CONFIRMS POOR WORKING PRACTICES DURING SHEEP DIPPING”. It highlighted “dippers hands or feet were used to immerse sheep on 48 farms” (7% of the total) and the head of HSE’s Livestock National Interest Group, (the sponsors of the report) said “this survey has confirmed our view of where the problems lie”.

It said, “Although contract dippers made up only 2.4% of the total they accounted for 10.6% of incidents”. This suggests the greatest single factor seems to be cumulative exposure. Many farmers were not aware of danger of cumulative exposure through inhalation until alerted by this piece in the Farmers Weekly fifteen years later. It is now accepted by HSE but not by DEFRA.

As the contract dippers were also found to be wearing better protective clothing than farmers the main route of exposure might have been inhalation, but face masks were not issued. The shortcoming of protective clothing available at the time is discussed on this audio clip from Countryfile from 1992.

There was no attempt in the survey to try to correlate ill-health with different chemicals used when dipping, apart from the observation that some farmers noticed less problems using non-OP dips. One main conclusion of the report was “Farmers need to be encouraged to substitute a hazardous product (OPs) with a less hazardous product (non OP)”. Sadly however for the last 23 years the ill-health of farmers affected has been ignored; all non-OP have been taken off the market leaving OPs as the only products available for dipping.

We include snapshots from the Northern Farmer’s March edition, which mentioned the work of the group in its front page story, the main feature inside and an editorial (above, centre) calling for an inquiry, listing three questions (above left) to which the group wants answers.
