Late-presenting cases of commercial raw food-associated TB in cats in the UK

Following the previously reported outbreak of raw food-associated feline tuberculosis (TB), July 2018 to July 2019, where 45 cats developed clinical TB and a further 77 had latent/subclinical infection1, 2, there has been ongoing monitoring for further cases of Mycobacterium (M.) bovis infection in cats fed a commercial raw food diet made of wild venison3. Despite the manufacturer issuing a full product recall, and ceasing to manufacture and sell the product in December 20181, we wish to report at least four cases of suspected late presenting raw-food associated M. bovis infection in cats referred to the authors between December 2019 and January 2021.
