• As @xander76 notes- blockchain can't do anything here that a centralized database wouldn't. That means using blockchain is about hype. Not results.
Tracing outbreaks is a lot easier w meat & other things where much of each lot is frozen & hangs out in inventory for months.
With leafy greens, you can use traceability records to find a suspected lot. But you may never be able to test & confirm it.
Sooooo it's really hard to ID a guilty party or find any actual evidence of wrongdoing. Especially the kind that's admissible in a court of law.
Plus, traceability doesn't *make* food safe. It just gives you a general finger-point towards the culprit when it's not.
For those not in the food biz- Costco is the 800lb gorilla of food safety.
Most grocery chains ask for "some kind of food safety audit." Costco requires you to actually get a *good* audit.
• There are a lot of entry-level "My First Audits" out there. Costco doesn't take those. You gotta get a big kid audit.
• There are a lot of audit co's out there. Costco actually keeps an eye on which ones are good, & only accepts audits from those co's.
Costco has an in-house food safety department. And they ACTUALLY SEND THEM OUT TO LOOK AT THINGS.
You'd think this is a common sense thing that every grocery retailer does. lmao it's not.
Number of shadow audits I've had from any other retailer: 0.
There may be other retailers that do this some, but Costco is tops in intensity of their program.
Costco dude is the reason I now have this amazeballs flashlight. Every other one I've had had a weak beam & disintegrated after 3 trips.
• Don't just take certificates at face value. Actually go out & spot-check to make sure the auditors & co's giving them out are doing the job properly.
• When you hire new people, bring them up properly. Transfer that knowledge & experience to the young'uns. They'll be your eyes & ears for decades- do it right.
I'm now a better auditor because of feedback I got from Costco. Because they know their stuff, and they're generous with sharing what they know.
Example: IMO a lot of the 2011 Listeria outbreak was related to fact that Walmart accepted audits with loopholes big enough to drive a truck through. Don't do ... that.
What's not in that list anywhere? FUCKING BLOCKCHAIN
