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
industry.

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
and farm chemicals 5 as well as for indications of possible                                   For further information on the NRE Survey of Victorian Navel oranges

                                       Support for this program was provided by the Victorian Government's Naturally Victoria
                                  Initiative. Significant funding was also contributed by the Murray Valley Citrus Board, Mildura.




4   All samples from Victorian growers were tested for: 36 Organophosphate compounds, 16 organochlorines, 10 synthetic pyrethoids, 21 fungicides, 4 carbamates, 9
    herbicides, 8 Dithiocarbamates, as well as for Buprofezin, Paclobutrazol, Piperonyl Butoxide, Propargite, Tebufenpyrad, Tetradifon and carbendazim,
5   The chemicals tested for as part of the packing shed survey were: Azinphos-Methyl, Carbaryl, Carbendazim, Chlorpyrifos, Chlorothalonil, Dimethoate, Diphenylamine,
    Endosulfan analytes, Fenthion, Imazalil, Malathion, Methidathion, Parathion-Ethyl, Parathion-Methyl, Pirimicarb, Procymidone, Propiconazole and Thiabendazole
6   Microbial contamination was assessed by testing for: E.Coli, Salmonella and Total Plate Count.
