Mr. Breed

To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to her answer of 29 January 2002,Official Report, column 241W, on genotype errors, if she will list the different types of errors that were discovered upon the retesting of the samples. [34863]

Mr. Morley

The errors which occurred at LGC were as followsProblems with the bar code reader on the robot handling the samples resulted in manual interventions which in turn caused errors in the identification of samples; A second robot was misaligned and this resulted in the incorrect transfer of samples, causing errors in the identification of samples; There were two sets of problems with the main testing methodology used by LGC. The first caused delays but not errors. The second was a technical problem with the assay. The latter resulted in the false reading of three samples.
