Poultry meat: improving food safety by improving chemical residue surveillance

Project Reference:

Status:

Completed

Commencement Date:

April, 2001

Project Duration:

48 months

Abstract:

Poultry are highly susceptible to the parasitic disease coccidiosis and veterinary drugs called coccidiostats are routinely used on a prophylactic basis in intensive poultry production. While they are very effective agents for this purpose, they have no nutritional value and have been shown to be toxic at high doses in laboratory animals. In addition, the toxicological information on these drugs is incomplete. While the likelihood of consumers being exposed to toxic levels is very low, best practice dictates that poultry food products should not contain residues of these drugs. It is therefore important for poultry and egg producers to ensure that this does not happen.

This project identified mechanisms by which the primary producer could control the utilisation of medicated feed in their production facilities to ensure that coccidiostat residues would not occur in their product. Specific analytical testing methods for the detection of these drug residues in poultry were developed during this project.

The outcomes of this project were evaluated at a later stage (Project Reference: 06-2007). In particular, the evaluation project considered the contribution of the "Guidelines for poultry producers on prevention of Nicarbazin residues in broilers" (Leaflet and Poster) to reducing the incidence of broiler liver samples non-compliant for Nicarbazin (> 200 µg/kg) in commercial poultry production on the island of Ireland.
