Results from the post mortem on the last fox collected a rather large fox (ruler is 18 inches long).
PathologistComment:
"The bodily condition of this fox together with a full stomach would indicate that it died of a fairly acute condition and that intestinal haemorrhage with digested blood extending from the stomach to the anus was the likely cause of death. Discussion with wildlife vets in UK and continental Europe and with toxicologists would suggest that second-generation anticoagulants (SGARs) could cause atypical anticoagulant posioning such as in this fox. This is probably the main differential diagnosis.
Natural England will now take this as a WIIS case and tissue samples will be sent away next week for toxicology.
Further Work: Histopathology Toxicology
So after all of its lack of interest and putting up all of its "don't care" arguments WIIS (Wildlife Incident Investigation Scheme are stepping in. We might have well had far more evidence before now had they bothered back in June.
So now I wait to see what happens (I doubt I will be informed).
Second-generation anticoagulants to be less vague five SGARs are currently authorised for use in the United Kingdom - difenacoum, bromadiolone, brodifacoum, flocoumafen and difethialone.
