◆ A baby girl of 9 months was found by her<br />

parents lying on floor. A broken plant pot<br />

which had compost in it containing<br />

chlorpyrifos was covering her face. The<br />

child appeared to have ingested an amount<br />

of compost. She vomited three times.<br />

c. PESTICIDE POISONINGS REPORTED TO<br />

THE NATIONAL HEALTH SERVICE (NHS)<br />

The National <strong>Poison</strong>s Information Service<br />

(NPIS) is a clinical toxicology service for<br />

healthcare professionals working in the NHS<br />

and is a service commissioned by the Health<br />

Protection Agency. The service consists of a<br />

network of units across the <strong>UK</strong>, providing<br />

information and advice on the diagnosis,<br />

treatment and management of patients who<br />

may have been accidentally or deliberately<br />

poisoned. Information on management of<br />

poisoning is available to registered medical<br />

professionals on TOXBASE, an Internet<br />

database or via a 24 hour telephone service<br />

for more complex cases requiring specialist<br />

advice 12 .<br />

The NPIS changed the format of its annual<br />

reports in 2004, now reporting data in the new<br />

format for a few types of pesticide active<br />

ingredients (Appendix 4b), so comparing<br />

* From creosote but note that creosote has been banned since 2003. However, some members of the<br />

public use ‘creosote’ generically to denote some sort of wood preservative so these may not all be<br />

creosote.<br />

earlier reports directly is not possible.<br />

Telephone enquiries to the NPIS do not<br />

necessarily represent numbers of poisonings<br />

because they are often precautionary only. The<br />

NPIS deals with all kinds of poisoning: in<br />

2004/5, the majority (67%) resulted from<br />

pharmaceuticals, and agrochemicals<br />

represented 1% of enquiries (other sources:<br />

industrial chemicals 12%, household 8%,<br />

cosmetics 8%, plants 3%).<br />

The total number of enquiries for pesticide<br />

poisonings in 2004-05 was 739, which included<br />

268 pyrethroids, 137 organophosphorus, 125<br />

paraquat (including two deaths), 120<br />

glyphosate and 89 carbamates. The top 20<br />

pesticides reported as responsible for incidents<br />

are listed in Table 2. In the previous year<br />

(2003-04) the figures were: 102 for glyphosate,<br />

175 for organophosphorus insecticides and 88<br />

for paraquat with one death.<br />

The NPIS is conducting a new surveillance<br />

programme specifically for pesticides 13 using its<br />

online service TOXBASE. The survey was<br />

commissioned by the PSD and HSE following<br />

work by the ACP on improving the surveillance<br />

of pesticide-related ill-health. In total,<br />

information on 588 pesticide-related exposures<br />

was collected from telephone and TOXBASE<br />

enquiries. This represents an improvement in<br />

the surveillance and reporting of pesticide<br />

poisonings. The scheme is voluntary, and it is<br />

unknown how many more cases would be<br />

reported if it was mandatory. Although<br />

information on headlice products was also<br />

collected, it was not included in the report to<br />

the PSD, because it is the Medicines and<br />

Healthcare Products Regulatory Agency<br />

(MHRA) which regulates these products.<br />

At their meeting in November 2005, the ACP<br />

considered the pesticide exposure monitoring<br />

report from the NPIS and commented that<br />

‘most incidents were relatively minor, and that<br />

those which were more serious tended to arise<br />

from intentional poisoning.’<br />

d. PESTICIDE EXPOSURES REPORTED TO<br />

LOCAL AUTHORITIES<br />

Incidents are still reported to local authority<br />

environmental health departments (Appendix<br />

4c) despite the publication by the HSE of an<br />

accessible leaflet 14 to the public on reporting. In<br />

2002, over half of the local authorities (see<br />

the second <strong>UK</strong> pesticide exposure report 5
