Fosetyl aluminium and phosphonic acid

Where does fosetyl-Al come from ?

Fosetyl-Al is a pesticide used as a fungicide to control various diseases on food and feed crops.
Fosetyl-Al has phosphonic acid (or phosphorous acid) as its main metabolite, which is regularly detected in poorly processed food matrices. This is the active ingredient analysed in our laboratory.

Which food chains are concerned ?

The wine sector

The fruit and vegetable sector (apple, pear, tomato, lettuce...))

Regulations

Fosetyl-Al is the active substance for which the highest number of MRL exceedances have been reported in relation to the number of samples analysed.
The use of fosetyl (Fosetyl-Al) is regulated and authorized in France and in Europe according to the regulation N°1107/2009. Regulation (EU) N°396/2005 and its successive amendments set MRLs for fosetyl in foodstuffs.

According to the review published by EFSA, "Peer review of the pesticide risk assessment of the active substance fosetyl EFSA Journal 2018;16(7): 5307' and the fact sheet published by BNN, 'Phosphonic acid, potassium phosphonate (potassium salt of phosphonic acid), fosetyl-aluminium May 2017', the phosphonic acid content in the matrices analysed may come from non-phytopharmaceutical sources (such as fertilisers) but also from the metabolism of fosetyl-Al.
