"Kvarøy Arctic joins IBM Food Trust blockchain to track Norwegian farmed salmon"

There's a woman in London who has looked into some of the pros and cons of distributed ledgers applied to food.
I wonder what she's up to these days.

From Silicon Angle:

Kvarøy Arctic, a major producer of Norwegian farmed salmon, today announced it will join the IBM Food Trust blockchain network to enhance the traceability of Arctic fish stock and increase consumer trust in its supply chain.

Using distributed ledger blockchain technology, Kvarøy (pronounced “Kwa-ray”) and IBM Corp. will enable corporate buyers and customers a transparent view of where fish came from — the journey the food took from pool to freezer or restaurant table – with a Quick Response code. The QR code gives access to everything that happened to particular fish, including its provenance history and even the feed it was raised on.

“Blockchain is the future when it comes to ending fraud in the seafood industry,” said Kvarøy Arctic Chief Executive Alf-Gøran Knutsen.

Blockchain technology uses widely distributed cryptographically secured ledgers to store and record transactions. In the case of tracking and tracing food, when a fish stock is taken from a pool the activity is recorded as data to the blockchain. Every time something is done to the food stock – such as transport, storage, processing, distribution and packaging – that event is recorded to the blockchain along with tracking information.

Once the data is added to the network, it is tamperproof and immutable, meaning that a restaurant employee or customer scanning a package of fish can trust that the data of every transaction all the way back to its origination remains unchanged.

The IBM Food Trust network uses that fact to provide a level of transparency that allows farmers, distributors and restaurants to get a view of what happened to the fish all along its journey. As a result, should any employee discover the fish had become tainted along the way – with bacteria or any other contaminant – the point of contamination can be rapidly identified and any potential batches affected can be isolated and recalled....

The woman was, of course the Financial Times' Izabella Kaminska who had some major impacts on my thinking.
Here's 2018's "Blockchain Could Help Restaurants Make Sure the Seafood You Order Is Actually What Lands on Your Plate"

I vaguely recall this story from a couple years ago. Something about cats and preventing diarrhea or something. It seemed to be one of the few uses of blockchain tech that actually made sense.
Take a look at this from Futurism and I'll see if I can find a post with felines and gastric distress....

Also the outro from January 2020's "Can Plant-Based "Pork" Sell In Muslim South Asia?":

If I was running strategy for one of these purveyors I'd have already started talks with Al-Azhar and gotten to know all the halal certifying bodies across the region.
And maybe registered that blockchain-based halal traceability startup I've always dreamed of.
"Here at GIGO Group, we believe..."*

*'Garbage in, garbage out', based on I. Kaminska's observation that if you don't get it right, at the very beginning of the chain, and at each step along the way, blockchain or not doesn't matter a whit. In other words, "Who's verifying the verifiers?"
