Fipronil Tainted Eggs Detected in Several European Countries

Aug 9, 2017 | Blogs, Food / Beverage | 0 comments

Fipronil Contamination in Eggs

News agencies all over the world are reporting a new food contamination issue regarding eggs which have been found to contain residues of Fipronil. According to Nieuwsuur, a Dutch news, and current affairs program, “The Fipronil scandal is a huge blow to the poultry sector. Millions of eggs are destroyed and 138 companies remain tentatively closed. But supermarkets also face great damage. In recent days all contaminated eggs have been taken out of the shelves.” CBS news has reported that contaminated eggs have been discovered in Belgium and in the Netherlands with other European countries now on alert.

What is Fipronil?

Fipronil is an insecticide which belongs to the phenylpyrazole chemical family, it is used in the application of flea, cockroach and ant control. It is the main active ingredient in many flea prevention pet care products. The World Health Organisation (WHO) has classed Fipronil as class II moderately hazardous pesticide.

What is the possible source of the Fipronil contamination?

According to the Food Standards Agency (non-ministerial government department of the Government of the United Kingdom), Fipronil has been used inappropriately in the cleaning of products used in the farming process on chicken farms. Furthermore, it states that Fipronil is not authorized for the use as a veterinary medicine or pesticide around food producing animals.

Fipronil and SCIEX

The detection of Fipronil in food products can quickly and accurately be achieved using the Mass Spectrometry solutions from SCIEX, showcased in a recent webinar on the Validating the Routine Use of High-Resolution Q-TOF LC-MS/MS for the Analysis of Pesticides in Baby Food”. The unique feature of this workflow is that the data was acquired using SWATH® Acquisition.

Why is SWATH so important? Well, the answer is that SWATH scans for all detectable analytes within a sample. Therefore in the analysis of eggs, if you were running a SWATH workflow even if you were not intentionally analyzing for Fipronil, you would still detect it and other potential compounds present which may have been omitted from your targeted workflow.Watch the webinar on how Fipronil and other pesticides are detected using the X500R >

Questions and answers to help improve your mycotoxin analysis

During a recent webinar I shared method details for mycotoxin analysis on the SCIEX 7500 system. In this blog i will share the Q&A for the submitted questions that we did not have chance to answer during the live webinar.

A 2-fold revolution: MS approaches for the bioanalysis of oligonucleotide therapeutics

In 1998, the US Food and Drug Administration (FDA) approved fomivirsen as the first therapeutic oligonucleotide therapeutic. This approval marked a revolution of mechanism of action discovered decades before finally coming to fruition. Since then, the landscape of chemical modifications of oligonucleotides, conjugations and formulations has evolved tremendously, contributing to improvements in stability, efficacy and safety. Today, more than a dozen antisense oligonucleotides (ASOs) and small interfering RNA (siRNA) drugs are on the market, most of which are designated as orphan drugs for treating rare genetic diseases.

Is “right first time, every time” a pipedream for metabolite identification by LC-MS?

If we lived in an ideal world, it would be possible to unambiguously identify metabolites using a single analytical experiment. This analytical technique would need to be efficient and easily generate the information needed from a routine assay that is also robust, enabling confident decision-making during drug discovery.
