PTs for pesticides in food: what do participants prefer?

The input from the market often indicates us the need of PTs for specific pesticides in food, but not always… so we decide to collect the needs of the laboratories through several surveys.

For honey and milk pesticides proficiency testing schemes we actively involved all our audience in programming, by proposing two surveys in order to collect the specific interests for pesticides PTs in these matrices. From the outcoming of our survey, with the aim of proposing a PT that really FIT-FOR-YOUR-PURPOSES, we decided to guarantee in the Test Materials the presence of some molecules that have been considered of high interest.

For vegetables, fish, eggs we performed an analysis of the molecules that our participants of 2021 analyzed the most, in order to establish which are the molecules more interesting for laboratories that come from all over the world. Out of this list, we chose the analytes that were searched the most and we decided to guarantee the presence of some of them in the Test Material.

So, as a result of all data collected, we adapted the characteristics of our proficiency testing schemes for the research of pesticides in several matrices. In fact, we established a NEW APPROACH, where the presence of some molecules is guaranteed and declared, while other molecules will remain unknown to the participants. In this way, who subscribes to our proficiency testing scheme will be sure to be evaluated for certain molecules of high interest, while maintaining the characteristic of analyzing an unknown sample.

Discover below the characteristics of our PTs for pesticides, corredated with some of the results of our surveys:

PT PESTICIDES IN HONEY
PT code: H2703

The Test Material will be contaminated with at least 5 molecules, where the following will be certainly present:

Glyphosate

Coumaphos

At least one neonicotinoid

In our survey, first of all, the participants were asked about the matrices of interest, they could choose among a list and express their preferences on a scale 0-5 (0= not interested at all, 5=extremely interested). The results showed as the most interesting matrices are honey, royal jelly and beeswax. Honey among these is for sure the most selected answer:

Then the participants were asked about their interest in a list of molecules; they could choose among a list and express their preferences on a scale 0-5 (0= not interested at all, 5=extremely interested). The answers showed as:

  • Glyphosate and Coumaphos were the most interesting molecules:
  • Several neonicotinoids were indicated as interesting molecules.
  • For all the molecules we decided to guarantee, they are often detected as positive in the routine analysis on honey by the participants of our survey.

PT Details:

  • The code for this PT is H2703.
  • 70g x 1 Test Material (in case the provided volume is not enough, it is possible to order additional material at a reduced price).
  • 70g of blank sample (matrice before spiking contamination) available at the cost of 59,00 euro.

PT PESTICIDES IN MILK
PT code: MI2704

The Test Material will be contaminated with at least 4 molecules, where the following will be certainly present:

Aldrin

Alpha-endosulfan

In our survey, first of all, the participants were asked about the matrices of interest, they could choose among a list and express their preferences on a scale 0-5 (0= not interested at all, 5=extremely interested). The participants showed interest for the following matrices: raw milk, lyophilized milk., powder milk and pasteurized milk. Raw milk among these is for sure the most selected answer:

Then the participants were asked about their interest in a list of molecules; they could choose among a list and express their preferences on a scale 0-5 (0= not interested at all, 5=extremely interested). The answers showed as aldrin and endosulfan were among the most interesting analytes:

PT Details:

  • The code for this PT is MI2704.

The presence of the following molecules will be guaranteed:

Fosetyl-Alluminium

 – Acephate

Vinclozolin

Coumaphos

Below you can find the percentage of interest of our participants of 2021 in the molecules that will be certainly present:

PT Details:

  • The code for this PT is VF2700, also a partial participations are available:

– VF2700/F if you are interested only in the research of Fosetyl-Alluminium

– VF2700/P if you are interested in the research of all other pesticides, without Fosetyl-Alluminium

  • 60g x 1 Test Material (in case the provided volume is not enough, it is possible to order additional material at a reduced price).

ADVANTAGES

  • 2 evaluations at the price of 1 participation!
    With all proficiency testing schemes for pesticides convenience doubles! In fact, 2 evaluations are included in each participation! In this way, with a single registration you can send 2 results, in order to evaluate 2 laboratory technicians.
  • Blank samples at a very low price are available!
    For all proposed matrices, there is the possibility to purchase the blank sample (the same matrix as the Test Material but before contamination). This samples are sold at a very low price, only 59,00 euro.
  • Super convenient prices!
    The proposed prices are really affordable, starting from 220,00 euro. Moreover, we are Always at disposal to check if any further ad hoc promotion can be available for you, just write to us your interests!
  • High Quality proficiency testing schemes!
    Progetto Trieste is an EN ISO/IEC 17043:2010 accredited international proficiency testing scheme, with participants that come from all over the world (see details about accreditation here). In order to guarantee the stability of our Test Materials, so that the assigned value can be more reliable, we provide mostly lyophilized Test Materials. Once the laboratory receives our Test Materials he can reconstitute them very easily (see our videos) and bring them to their original form. In this way we can guarantee that all participants receive the same Test Materials!

The surveys have been a great instrument non only for improving our programme for 2022, but also for understanding new needs of the market and programme new PTs for the future. We collected interest also on new matrices and analytes, that we hope to be able to include in our future proposals.

If you want to be part of the change, you can still contribute, our surveys are still opened:
