Yeah after the previous story, about 6 months later they came to upgrade basically the entire grid section in our area. We had a talk to the engineer and she had been able to use our section as justification for getting some sort of brand new and very expensive testing equipment.
Our neighborhood was built in the early 1960s. So at the time it was about 50 years old, and the electrical usage of homes then was vastly different than it is now. Unlike modern homes with power outlets every 6 feet or so on every wall, we have two outlets per room, if we’re lucky. She seemed very happy that we had pushed the issue because apparently that equipment had been requested for years before she finally had a real world justification that management would finally approve.













For a real answer, instead of the usual Internet and “US bad” useless comments… yeah things like metal detectors and X-rays are pretty standard for a lot of food manufacturing.
However, just because things are standard, and even installed and used, that doesn’t guarantee that it issues are noticed immediately. Things do fail, sometimes silently depending on the design, and that might not be noticed immediately, or employees on the line ignore issues instead of dealing with them. Sometimes, things are just caused by laziness or incompetence, not for intentional reasons.
And sometimes it’s just a difference in who’s expected to verify quality at various stages of processing a product. If the final processor and packager isn’t likely to cause a particular issue via their equipment and process, they might not check for those issues, instead expecting their suppliers to do so before they get the material. Like if the final company just puts packages the final product in plastic, they might not be checking for metal fragments because their equipment doesn’t have any risk of doing that. And the previous suppliers might not be checking because they expect the final company to check the end product is after all processing. So the end result is no one actually checked for it.
