I'm afraid no. The sequence of "there is an elevated number of EHEC/HUS cases occurring in Northern Germany" to "it came from this organic darm in Bienenbüttel" took the German authorities a month, and they are no iditots. From that point via "it was in a sprout mixture" via "it was on the seeds, and not introduced while growing the sprouts" and "it was feungreek to begin with" to "it was THIS fenugreek batch from Egypt" took another month.
If there is no clear designation of origin written on a packet of seeds, I don't think anyone can assure you anything. If you really want to exclude any risk here, you may want to avoid eating sprout mixtures altogether. OTOH, I am not aware of the epidemic sapping into the US, so I suppose there are either no fenugreek seeds from Egypt exported to the US, or the US didn't happen to catch the contaminated batch.
Mind you, it was one batch that was contaminated; that doesn't necessarily throw a bad light on the Egyptian seed industry. The contamination event may have been really subtle.
For someone who works with seeds, you needn't worry. Just stick to what you learned about personal hygiene for a food worker, and you'll be fine.
Over here, the epidemic is winding down. The daily reprtrs from which I drew my numbers have been dicontinued.
