I don't keep up with the day to day developments on the e-coli wars, because as you point out the numbers are small, but here is my take on the needle/blade tenderization issue.
Some cuts of meat are tough by nature or riddled with connective tissue. Some of this ends up as cubed steak after being run through what looks like a wood chipper. This meat is easily identified by texture, and to the best of my knowledge would always be called cube/cubed steak or something similar.
Another method is to use a needle device, or jacarder. This is used to break up connective tissue on some cuts. Some places may use it on everything, but I don't see the point. I've seen it used a lot in restaurants for end cuts from a strip loin. There is a section where the ribeye and the loin overlap and it shows up as a shrinking(or growing) segment in cut steaks. The area where this segment is located (usually just the first 4-6 steaks off of a loin) will usually get jacarded in a restaurant setting to break up the fibrous tissue and make these steaks usable. I even do it at home when I buy or cut these steaks.
