Pesticides in egg (incl. fipronil, nicotine, cotinine)

The test material consists of liquid whole egg from chickens. The eggs are homogenised, spiked with pesticides and deep-frozen thereafter. 

Common multi-method pesticides, which are relevant for eggs are included in the scope of this ring test. The scope of relevant pesticides is provided in advance. 

The analysis of fipronil and fipronil sulfone as well as of nicotine and cotinine are available as an additional module.

The analytical data are assessed with respect to

  • the correct identification of the spiked pesticides (multi-method pesticides),
  • the comparability (z-score), and
  • the trueness (70 to 120% of the spiked level).
