The National Food Residue Database- information on the safety of our food The National Food Residue Database (NFRD) is a comprehensive publicly accessible resource that presents data on contaminant residues in a broad range of foods in Ireland. The information is readily available via . The NFRD has become a reliable, comprehensive and easy-to-use resource on chemical contaminants in food for the benefit of the food industry, researchers, regulatory agencies and the general public. This report summarises the key findings from the database between 1998 and 2005. Project code FS018, Final Update
The unique feature of the NFRD is that it collects,
