Unless you only ever buy fresh produce you are going to consume imported produce and product. Read the packet it is an eye opener...always buy meat from your local butcher and never ever buy frozen meat or fish if you want to avoid imports.
I was buying Coles brand whole peeled tomatos, their canned kidney beans and other canned pulses until I read the label...it was all fully imported from Italy.
I now buy local canned product and pay the extra...instead of being a skinflint.
Most manufacturers admit to mixing imported and local product in their products. It aint new.
25 years ago I was involved in transporting Berri fruit juices from the factory at Balcatta in WA to distribution warehouses. We would often pick up dozens of 205 litre drums of frozen orange juice imported from Brazil for the Berri factory to mix with local produce.
