Meat is not easy to track on the blockchain. Tracking goods' provenance is indeed a good idea but the weak spot is the "oracle". The easiest to understand "oracle" is a RFID / NFC chip that crosses the "physical - blockchain" barrier: it is physical and can be physically attached to the good to be tracked on one side. Yet it is a chip and can thus communicate with the blockchain.

Such a device can work well for tracking luxury goods for instance - if a NFC chip is sewn in a Gucci gown so well that one cannot cut it out without destroying the gown itself then the link is solid and you can use it to track the original and fight counterfeiting. If someone comes to you to sell you a Gucci gown without the NFC chip you know it's a fake

With meat this works less well - you can put NFC chips on the refrigerated truck that transports the meat but you can easily imagine that fraudsters could keep the chip but replace the meat inside the truck with lower quality meat
