Wellcome Trust Safer Storage of Pesticides Project
A community-based trial of safer storage to reduce pesticide self-poisoning in rural Sri Lanka
Pesticides and suicide
Pesticides are commonly involved in suicide. It has been estimated that nearly a third of the over 800 000 suicides in the world each year involved pesticide ingestion. These deaths particularly occur in rural areas of developing countries where there are large numbers of small farms and where pesticide use is important for sustaining crop production.
One issue is that pesticide containers are often left lying around in households making the pesticides readily available for suicidal (and accidental) ingestion. We have conducted a pilot study in Sri Lanka jointly with a community support organisation (‘Sumithrayo’) to assess the acceptability and use of lockable boxes for safer storage of pesticides (Hawton et al. 2009). We are now involved in an international collaborative study in which a cluster randomised evaluative trial of storage boxes is being conducted in 162 villages in Sri Lanka (Pearson et al. 2011).
