Notice of Withdrawal of Certain Lots of BioLogics Beef Recipe for Dogs

On September 19th, 2025, we made the decision to withdraw two lots of BioLogics Beef Recipe for Dogs after testing indicated the presence of Listeria. We have notified all customers and will continue to update this page with more information as we have it.

Notice to Customers:

At Darwin’s Natural Pet Products, the health and well-being of pets is our highest priority. Recent testing on samples from two lots of our BioLogics Beef Recipe for Dogs has identified the presence of Listeria monocytogenes.

While the risk to pets is low, out of an abundance of caution, we are voluntarily withdrawing these products, and asking customers to discard any remaining products from these lots.

Products Affected:

Darwin’s BioLogics Beef Recipe for Dogs

● Lot Number 11826; Manufacture Date 7/7/25

● Lot Number 11895; Manufacture Date 7/29/25

No other Darwin’s products are affected by this withdrawal.

While Listeria monocytogenes poses minimal risk to healthy dogs, it can present health concerns for pets who are very young, elderly, or have weakened immune systems. We are taking this step proactively to ensure the continued safety of our customers’ pets.

We deeply value the trust you place in us to nourish your pets. This withdrawal reflects our ongoing commitment to rigorous quality control and transparency, and we are actively investigating new ways to strengthen our safety procedures.

Thank you,

Darwin’s Natural Pet Products
