Fatty Acid Profiling (FAP) is used by our crop health experts to identify bacterial isolates. Bacterial cultures are raised onto specific media and analysed by gas chromatography using a Microbial Identification System (MIDI system). The profiles generated are then compared against commercially available FAP libraries as well as our own in-house libraries generated using isolates from the National Collection of Plant Pathogenic Bacteria (NCPPB).

The testing procedure is accredited by the United Kingdom Accreditation Service (UKAS) to ISO17025 standards. This test has a rapid turnaround of just 7 working days after your samples receipt by our scientists.

When sending plant pathogens and invertebrate samples from outside England and Wales for testing please email the Crop health team (crophealth@fera.co.uk) who will issue you with the relevant Letter of Authority to ensure your samples are not delayed upon entry to the UK.

Submitting your Sample

When submitting your sample please follow the guidelines outlined within our sample shipping information.

The relevant signed sample submission form must be included (in a separate bag if sample is damp); failure to send a sample submission form may result in a delay of your sample being tested and make diagnosis more difficult. To help us process your samples in the most efficient way please fill in as much information as possible on the relevant form below. Please ensure you provide your email address, 'Your Ref', 'Purchase order no' and 'Name and Address for Invoice' in the sections where applicable.
