According to this article: http://www.geocities.com/crayfishdisease/pages/info_pa/virus.html, it is not advisable to feed raw/uncooked shrimp to crayfish or other crustaceans.
"[FONT=Times New Roman, Times, serif] However, a number of viruses are known to be highly pathogenic to freshwater crayfish, including white spot syndrome virus (WSSV) which has caused massive losses in shrimp aquaculture around the world. WSSV can be transmitted to freshwater crayfish simply by feeding them with infected tissue. There was one case reported where feeding shrimp infected with WSSV to captive crayfish resulted in up to 90% mortality"
I would highly recommend against feeding raw shrimp in any tank that has a crayfish or shrimp living in it.
If you are feeding cooked shrimp this is not really an issue, as cooking destroys the virus. If the shrimp you are feeding is pink/red then it has been cooked, no worries.
