UK DEFRA LINK Food Safety Programme
RBR is currently part of a joint UK DEFRA LINK Food Safety Programme /FSA funded project to assess the Fate of Fusarium Mycotoxins in the Cereal Food Chain.

One purpose of the project is to contribute data addressing the fate of Fusarium mycotoxins during commercial food processing and assist with an appraisal of legislative limits. The information generated from this project should help food companies to comply with the new regulations and so help them to best protect the consumer.

As part of the project a brief evaluation of RIDA®QUICK DON, a lateral flow device for screening cereals for deoxynivalenol at the EU proposed legislative limits was performed. 12 participants took part in the study and each were provided with 9 blind samples of cereals including wheat, maize, barley and oats for testing using RIDA®QUICK DON at 500ppb. One positive sample, Maize 73 was provided to confirm that there was no problem in operating the test.
With RIDA®QUICK DON the presence of a test line following analysis represents a positive result above the 500ppb cut off level. No line indicates a negative result below the cut off level of the test. The screening level of the test can also be adjusted by changing the sample dilution prior analysis.

Out of 108 analyses, 107 agreed with the HPLC reported result for each sample and except in one instance, the presence of DON at 500 ppb or above was correctly identified.
A positive for maize at 100 ppb was obtained by one participant and confirmed by repeating.

In conclusion the RIDA®QUICK DON lateral flow device was found to be suitable for screening a range of cereals above or below a 500ppb level and is recommended for use by the cereal industry.
