The report is actually for Gumabone which is manufactured by the NYLABONE people. Gumabones are softer than the harder Nylabone product.

If you make sure it is a super hard original Nylabone, you should be OK. Gumabones are softer and break off in large pieces which the dog ingests and has a hard time passing because they don't break down.

The only thing I think you need to be leary of in the original Nylabone is that they are sooooo hard, the dog can actually wear down teeth or crack a tooth.
