The 4 missions of SOMEAT

1st SOMEAT mission

the contaminant status of organic meat. SOMEAT thus aims to provide a first reference study to address the need for a scientific basis in the debate on the presumed health benefit of organic production in meat. For a proper calculation of the right number of samples to be collected in order to be representative at a reasonable cost, the sampling plan should also allow for time and cost of sample analysis for the five classes of contaminants (organic pollutants, pesticides, heavy metals, mycotoxins and antibiotics), each comprising several, and sometimes many entities to be analysed.

2nd SOMEAT mission

the chemical risk for conventional/organic meat consumers. This issue requires taking into account the main modulating effects of technological and physiological processes on the toxicological impact of contaminants.

It will come to:

  1. investigate the impact of cooking on the fate of the priority list contaminants
  2. Using an in vitro digester, SOMEAT will investigate the influence of the cooked meat matrix on the bioaccessibility of target contaminants ;
  3. investigate mixture toxicity on cell cultures of human enterocytes, hepatocytes and hepatomes exposed to realistic mixtures of meat contaminants.

3rd SOMEAT mission

the socio-demographic variables explaining the consumption of organic meat. The main impediment is the absence of precise data on the consumption of organic meat. The national databases on purchasing or consumption are not precise regarding this type of consumption because of the relatively low purchase frequency and the absence of precise coding of organic meat. Through a survey and a lab experiment, SOMEAT will provide clues about the consumption of organic meat.

4th SOMEAT mission

develop new analytical methods based on the profiling of targeted biomarkers to ensure the chemical safety of meat by tracing the exposure of the meat chain to contaminants. The first hurdle is to determine potentially relevant biomarkers. Preliminary metabolomic work pointed to the relevance of metabolome profiling for back-tracing rapidly metabolized compounds. Besides metabolomics, transcriptomics may reveal the expression of targeted genes involved in cell detoxification mechanisms.
