Cattle steroid abuse identifiable with new test
New innovative tests have been developed by scientists at Queen’s University Belfast to identify the use of steroids in an illegal manner in the European beef industry, as per a study.
The new tests are not only economical but also more accurate and easier than the conventional drug tests for tracing the presence of illegal steroids in cattle.
The study appeared in the scientific journal Analytical Chemistry and was led by Professor Chris Elliot, the Director of the Institute of Agri-Food and Land Use at Queen’s.
From Sciencedaily.com:
Using a commercial blood analyser commonly found in hospitals, the researchers measured 20 different chemical markers, including proteins and cholesterol, in cattle treated with and without the commonly used steroids testosterone and oestrogen over a 42-day study period.
The new test detected the presence of the steroids with a high accuracy rate – between 91 and 96 per cent.
Professor Elliot said: “In recent years, a trend of administration of very low dose cocktails of naturally occurring hormones has made conventional forms of analysis even more problematic.
“Even if minute traces of steroids can be detected, proving definitive illegal administration under these circumstances is close to impossible.
“The ability to detect evidence of such administrations using metabolic markers would be a major scientific advance.
Professor Chris Elliot, the Director of the Institute of Agri-Food and Land Use at Queen’s said that single steroid administration means that a lowered metabolic response was generated as compared to what would have been achievable via cocktail hormone treatments that are presently abused in Europe.
