Methods for antibiotic residues in foodO'Keeffe, Mandy J.; Walshe, Michaela; Horne, Elizabeth; O'Keeffe, Michael; Foran, Shane; Lardner, Caroline; Daly, Tracy; Kane, Marian (Teagasc, 2001-04)A comprehensive capability to test for residues of veterinary drugs is an important support for the Irish food industry. There is a requirement for food manufacturers to demonstrate the compliance of their products with stringent customer specifications. In addition, legislative requirements are becoming more exacting both in terms of the range of substances covered and the lower residue levels to which test systems must measure.
Supercritical fluid extraction of veterinary drug residues from meatO'Keeffe, Mandy J.; O'Keeffe, Michael; Department of Agriculture, Food and the Marine, Ireland (Teagasc, 1999-10)Extraction is a key step in the analysis of food samples for residues of veterinary drugs. Over the last ten years there has been increasing interest in alternatives to the use of organic solvents for sample extraction. The development of supercritical fluid extraction (SFE) for the determination of residues in meat provides alternative methods, which may be automated and which have attractive properties such as avoidance of organic solvents and increased speed of extraction. This project is a jointly-funded United States Department of Agriculture and Department of Agriculture and Food activity with the objective of developing robust SFE procedures suitable for the quantitative recovery of ß-agonists (illegal growth promoters) from animal tissue. Fundamental aspects of SFE in its application to residue analysis are also addressed.
