I am sure that that is absolutely true, as it is of other retailers. Waitrose, for instance, wished to point out that its contracts require its own-label burgers to be made on the first run in the morning, to ensure that there is no cross-contamination from other products later in the day. Retailers take the matter terribly seriously, and we should not give the impression that they do not, because that would be a false impression.
Ultimately, however, the Irish authorities did pick up a serious example of adulteration, and I congratulate them on that and on communicating the facts to us, so that we and others have been able to work closely with them to investigate what happened. While I do not diminish the point made by the hon. Member for Cardiff South and Penarth (Stephen Doughty) about those whose religious dietary requirements may be affected, the trace findings of porcine and equine DNA elsewhere were a much lower level of contamination than the burger containing 29% horsemeat, which appears to have been a case not of cross-contamination but of deliberate substitution.
