For processing, oysters were scrubbed under running potable water and shucked by separating the adductor muscles from both valves. They were then gently rinsed under running potable water to remove debris and the meat turned to expose the cupped side. Oysters were placed in compostable corn starch oyster trays (JMP Holdings Pty Ltd, Victoria, Australia) (12 oysters per tray) and placed within unsealed polyethylene/nylon pouches (Tailored Packaging, Rhodes Waterside, New South Wales, Australia) with the end of the bag folded to prevent dehydration. Once processed, all oysters were stored at 4 °C until analysis for up to seven days.
