Growth-promoting hormones are widely used amongst livestock farmers to produce leaner meat, generating greater return for the weight of the cattle. Over use can lead to trace residues of these hormones ending up in the food chain.
Randox Food Diagnostics have developed a rapid screening method, which can rapidly detect multiple growth promoting compounds in a single sample of urine after a simple dilution step.
