The German 'Lebensmittel- und Veterinärinstitut (food and veterinary)Oldenburg' in 2012 investigated 37 samples of deep-freeze vegetables for residues of plant protection means. No residues of plant protection means were found on 38% of the samples.
21 samples of deep-freeze peas, 4 of broccoli, 4 of cauliflower, 3 of French beans, 3 of leeks, 1 of Brussels sprouts and 1 of red cabbage with apple were investigated.
Five samples originated in Belgium, one came from Germany and of the rest the source was unknown. Five of the 37 samples (4 times peas and 1 red cabbage with apple) originated from organic agriculture.
No residues of plant protection means were found in 14 samples (7 x of peas, 3 x of cauliflower, 2 x of broccoli, 1 x of leeks and 1 of red cabbage with apple). All samples from the organic agriculture were part of this as well. Furthermore none of the samples exceeded the maximum allowed quantity of residue of plant protection means.
During the investigation of the vegetable samples 17 different active substances were found in all. The fungicide Carbendazim was found most of all, namely in eight of the 37 samples. In 68% of the samples a maximum of one working substance was established.
