WEBINAR on demand: phosphonic acid in food origin
Entry routes in food and feed from organic farming
Findings of phosphonic acid in organic products are interpreted as residues of possible illicit agricultural applications of the fungicides sodium and potassium phosphonate or fosetyl-Al. In the webinar, Dr Werner Nader will present a study based on published scientific findings and an anonymous evaluation of the data from the Eurofins laboratories for food and feed testing in Germany. This shows that there are more entry routes for phosphonic acid than just agricultural applications. These may be of natural origin or can be possibly traced back to household and industrial contaminations. In many cases, the interpretation of the findings as pesticide residues is therefore not justified. The results of the study can be viewed in the scientific journal "Food Control", Elsevier publishing company.
The lecture by Dr Werner Nader was presented at BIOFACH 2023. Due to high demand, we offer the lecture here as a free webinar on demand.
