Regulator flags concerns about chemical used on Aussie berries
Australian children aged between two and six could be at risk due to a chemical sprayed on berries, a regulator has warned.
A national regulator has raised concerns about a chemical used on popular berries that is potentially harmful to young children.
The Australian Pesticides and Veterinary Medicines Authority (APVMA) suspended the use of chemical products containing dimethoate for use on blueberries, raspberries and blackberries.
New research indicated Australians’ consumption of berries has significantly increased since the incesticide was last assessed in 2017.
Authorities found the use of dimethoate no longer left an adequate safety margin to meet the maximum acceptable level of exposure.
APVMA advised children aged two to six who ate blueberries, raspberries and blackberries within one week of harvest were at risk of exceeding the safety limit of the chemical.
“Based on these consumption figures, the APVMA reassessed the potential level of dietary exposure for all chemicals approved for use in these berries and found that use of dimethoate following the approved label directions does not leave an adequate safety margin between the possible level of dimethoate residues and the maximum acceptable level of exposure,” a spokesman said.
“APVMA considers the level of residues detected are unlikely to pose a serious risk to human health but has suspended use as a precautionary measure.
“Berries remain safe to eat.”
The regulator will allow growers to continue using dimethoate if they wait 14 days before harvesting blueberries, raspberries and blackberries to reduce harmful effects from the chemical.
US health authorities warned high or repeated exposure to dimethoate, which is used to kill insects, flies and mites, can effect the nervous system, personality changes, as well as cause organophosphate poisoning, which can be fatal.
But an APVMA spokesperson said they only approved the use of products that are safe and ensures a substantial safety margin between potential agricultural chemical residue exposure and the levels that could be linked to an adverse effect.
“The decision to suspend some dimethoate uses was taken to restore this significant safety margin,” a spokesman said.
“There is no evidence that harmful levels of dimethoate have been present on berries. Australian grown berries remain safe to eat.”
Berries Australia Chair Anthony Poiner said the industry welcomed the clarification on the use of dimethoate on berries.
“Mindful of concerns about cost increases and supply challenges as a result of restriction of pesticide options, the industry has been working for clear guidance and alternative solutions as part of ongoing investment in sustaining and enhancing safe and sustainable production practices,” Mr Poiner said.
“The berry industry has acted to minimise pesticide use, mainly by adopting integrated pest management strategies and increasing biological controls to reduce chemical dependence.
“Integrated pest management incorporates biological controls (predatory mites and insects), protected cropping through nets, and innovative farming practices, using chemical pesticides only as a last resort, to ensure the quality of berries sent to market.”
