Tell us then if Japan is using your test and you say it will pick up BSE prions at any age  then why did the Japanese  say the testing they have been doing didn't show any results in under 20 months and therefore they agreed to drop the testing of 20 month and under? Why wouldn't they just tell the US that they wanted them to us your test if they want to export to Japan. Why would they go through all the work of changing their testing protocol if all they had to do was have the US use your test?

 About the feed mills if they use cattle by products in their pig and chicken feed there in not law against it yet. If they are using pig and chicken in cattle feed I don't know of any law against that either yet  but if they are using cattle by products in cattle feed and selling it as cattle feed that is what is illegal.   If the producers know this and are buying it to feed to their cattle then I say throw them all in jail and throw away the key.  If you know this is happening for a fact then TURN THEM IN  as we don't need that knid of stupidity in our industry.
