Professor Richard Tedder stated in his statement to the Inquiry ""Personally, I would have recalled, prevented or very strictly controlled the use of imported commercial blood products, especially those from the USA, which were known to have a significant risk over and above the expected. If the same was to occur with a British product, then clearly recall would be appropriate. At the Middlesex we would only have used such products if it was the only option to avoid serious harm to a patient".
