Enforcement Residues Monitoring Programme - Winter Lettuces

The Pesticides Safety Directorate undertook winter grown lettuce enforcement programmes in 2001/02, 2002/03 and 2003/04  involving sampling on growers’ premises and retail premises.

Background

The purpose of the monitoring was two fold:

1. to ensure that residue levels do not exceed the legal level; and
2. to indicate if there are any incidents of misuse of pesticides on lettuce.
3. to indicate if there are any incidents of non-approved use of pesticides on lettuce.

Such monitoring is important as it ensures, not only that good agricultural practice in undertaken, but also that consumers are confident that our foodstuffs are sound and reliably produced.

In 2003/04, the samples were analysed for residues of quintozene, chlorothalonil, dimethoate, oxadixyl, vinclozolin (none of which are approved for use on lettuce in the UK), cypermethrin, inorganic bromide, iprodione, metalaxyl, pirimicarb, propyzamide, and tolclofos-methyl (to check for compliance with UK/EC or Codex MRLs).
