REPORTER: Yes, hi, Doctor. Is the USDA saying that Canadian animals that are born before March 1, 1999, are not safe to import to the U.S.?
DR. CLIFFORD: Basically, what we're saying is, is based upon our assessment and analysis of when an effective feed ban went into place, the date of March 1, 1999, was determined. That was based upon Canada putting a feed ban in place at the same time the U.S. did. In August of '97 we looked at having six months of a practical implementation date, and then we added an additional year to that date for the normal marketing period where you would expect feed to be cycled through in the cattle in that system.
So basically there's where we came up with the year-and-a-half date. So it's not saying that cattle born prior to that are unsafe. It's just saying that we're looking at that as an effective feed ban date and we're just accepting live cattle after that date.
REPORTER: As you know, case number 4 and 5 were born after that March 1, 1999, date. They were both born in the year 2000. So some people would say that you've just kind of, on the back of an envelope, put six months plus one year, to use your words, and come up with a March 1 date. You know, what other justification can you explain to me as to why you chose that date?
DR. CLIFFORD: Well, the justifications that we made were based upon what I gave you. We have previously, under the minimal risk rule one that we came out with, we evaluated Canada's effective feed ban and determined that they had an effective feed ban during publication of that rule, and that was based upon our personal investigation and knowledge of that system and information that was provided to us.
They have the authority, they have the infrastructure, plus they've established our performance standards within that system to be able to effectively monitor that system, make sure there's appropriate training. As you know, with any type of system there's no such thing as 100 percent compliance.
And if we'll look throughout internationally we know that countries that have had other effective feed bans put in place will find case after that effective feed ban.
REPORTER: But does the rule address the fact that there were three cases, the latest being April 22, 2002, when there was a BSE case?
DR. CLIFFORD: There is, the rule takes into account that three cases occurred after that feed ban date, and again the risk -- when you look at these things you can't look at one particular issue. You have to look at it in total through all the mitigations, whether you're talking about SRM removal, to feed ban, to feed manufacturing, to rendering inactivation, to biological limitations. So you have to look at the whole system as a whole when you're looking at the level of risk. And we have found, based upon that risk assessment, when you look at this as a whole that the risk is extremely low.
