It's more like: food processing tool A is known to be defective. We ask employees of this restaurant and supply chains to avoid food processing tool A. This seems eminently reasonable. The question is whether the tool is in fact defective.
Sure, kind of, if the supposed defect is only one of the reasons, and if ‘food processing tool A’ was a hot-button topic that many people have deeply philosophical and ideological opinions about. Oh, and for good measure, if the proposed ban is for ‘food processors’ in general, and a material amount of pushback is coming from a bunch of greybeard industrial cooks that used one particular food processor a couple of years ago, weren’t all that impressed, and have been railing against food processors ever since.
That's just it though. The tool(s) aren't necessarily defective. Just because you can chop off your own hand with an chainsaw or do a botch job of sawing a plank of wood because you weren't watching what you were doing with the electric saw, does not by itself make the tools (Chainsaw, Electric Saw) defective.
