Brief outline of the project:

The aim of the project is to check for the possible existence of endogenous thiouracil. Although the use of antithyroids to fatten livestock is prohibited, control laboratories have been finding a low dose of thiouracil in urine samples regularly for some years now. It is important to know if this is endogenous or if it has been administered illegally.

The primary objective of the project is to determine a “baseline threshold” above which the presence of thiouracil can be considered as suspicious. The secondary objective is to give animals different types of food to see if any of them could cause production of thiouracil.

The project is also aimed at trying to identify biomarkers that could enable us to differentiate between endogenous and exogenous thiouracil.

Role of the CER: 

The CER has an important role in this project. It is in charge of in vivo experiments on bovines fed with different types of food containing brassicaceaes in which the precursors of thiouracil are present. The CER is also responsible for developing an analytical method of confirmation by LC/MS-MS.  --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
