The hon. Gentleman makes a great point: I cannot provide that particular piece of evidence, but what I am told by health organisations and others is that ingestion of lead over a period can be quite dangerous. As others have said, as a responsible society that recognises the inherent dangers, we have already taken action and regulated to cut lead from petrol, paint and water pipes, so most exposure to lead in the general population now comes from diet. However, despite the evidence and our previous moves to regulate other sources of exposure, we have not yet completely banned the use of lead by shooters. Instead, we have stopped short, although in response to the UK’s obligations under the African-Eurasian migratory waterbird agreement to phase out the use of lead shot for hunting in wetlands, it has been illegal to hunt certain wildfowl over certain wetlands since 1999. The long and short of such patchy regulation is that lead continues to find its way into the food chain and on to our dinner plates. Compliance with regulations is sporadic at best, and most consumers are simply unaware of the contamination risk to themselves and wildlife.
My hon. Friends have alluded to studies showing that 76% of game bought from supermarkets, game dealers or game shoots have lead shot fragments present. Indeed, a DEFRA-commissioned study found that 70% of ducks sampled were illegally shot with lead. If that were not enough, almost half of respondents to a British Association for Shooting and Conservation survey admitted that they did not always comply with the law. To top it off, a repeat study in 2013-14 showed that compliance had not improved, revealing that 77% of sampled ducks had been shot illegally with lead. Yet, to the best of my knowledge, there have been no primary prosecutions
and only one secondary prosecution for non-compliance with the regulations. That is a law that is not working in this land, so we need a change.
