The risk of importation of AMR into Australia via uncooked prawn commodities has not been assessed.
Given the existing pathway of dissemination of prawn commodities into waterways via disposal (berley)/use (bait) the release and establishment of AMR microbes could impact on prawn hatchery performance, where juvenile stages are particularly sensitive to bacterial diseases such as Vibriosis. Should AMR enter hatcheries via the use of wild broodstock, water or aerosol pathways it could contribute to great challenges in maintaining reliable hatchery production for the entire prawn farming sector, for it could render the currently available antimicrobials useless.
There is growing concern about the emergence of antimicrobial resistance in humans, and the pathways for its entry and establishment.
The trade of importing uncooked prawns for human consumption was temporarily suspended from early January to early July 2017 after the WSSV outbreaks on the Logan River in Queensland and import compliance breaches were identified. With this trade re-opening the pathway for potential entry of AMR on live bacteria warrants assessment.
A further pathway for generating enhanced risk of antimicrobial resistance is through allowing human consumption of commodities with sub-therapeutic levels of antibiotic and agricultural chemical residue.The Australian Prawn Farmers Association (APFA) are seeking to better understand the presence or absence of a range of chemical residues in imported prawn products. Insufficient data has been collected as part of the National Residue Survey to give industry confidence that the imported products do not pose a potential health risk to consumers, and hence do not pose a risk to the marketing and sales of prawns generally. Data is needed to inform the submission from the APFA to the review of the Commonwealth Import Risk Assessment of uncooked crustacean and Australia's food safety regulator (FSANZ).
