throughout the navel growing season, some growers may
use chemicals to control pests and diseases, and to
maintain product quality. Overall, less than 1% of the
samples from Victorian growers contained residues above
the domestic MRL standards and in fact, 95% of
V ictorian samples recorded no residues at all in
the produce. This is a great result, as these samples
were tested prior to being washed as part of the normal
packing shed process, with the aim of identifying any
potential risks for future management by the citrus

In the second part of the program, more than 100
samples of export-ready navels were taken from the
dispatch section of 23 export certified packing sheds.
These samples were tested for residues of post-harvest
