QS – Report 2012
Outlook 2013
Residue monitoring
A total of 11,158 analyses were conducted in QS
Residue Monitoring in 2012, 30.7 percent on the
producer level and 69.3 percent in wholesale
businesses. No active substances of any kind were
found in 46 percent of the examined samples. Of the
samples that contained active substances, more than
one substance was detected in 68 percent of them.
Together with the German Fruit Traders’ Association
(
DFHV), QS publishes the results of residue
monitoring for fruit and vegetables once a year.
16,059
samples from 66 countries were evaluated
for the
monitoringreport 2013
. 40
percent contained
no detectable residues whatsoever. The proportion
of samples in which the maximum residue level was
exceeded lay at 0.9 percent for goods of European
origin and 2.8 percent for goods from third countries.
The
monitoringreport 2013
contains among other
things detailed evaluations of the residue situation
with plums and carrots. No residues of any kind
were detected in 57 percent of the 263 plum samples
examined. A quarter of the samples with residues
contained only one active substance.* A total of 21
different active substances were analysed.
The 441 carrot samples examined originated from
six European countries and Israel. Almost half of the
samples were free of residues. Overall, 25 different
active substances were detected. For 65 percent of
the detected active substances, the percentage of
the maximum residue level present was under 20
percent per substance. On average, 9.7 percent of the
maximum residue level was present.
