Nuts are a delicious and filling snack and a tasty addition to a cookie, but they’re a lot less healthy when they come with a generous coating of Salmonella bacteria. That’s the case with macadamia nuts from Diamond, which have been recalled after routine testing turned up bacteria on a bag of nuts.

The good news is that the bacteria turned up in routine testing, and hasn’t yet been linked to any illnesses among customers out in the real world. This may be because the bags included in the recall are marketed for baking, which might heat the products up enough to kill the bacteria.

However, two different sizes of the nut packaging have been recalled as a precaution, and those include:

4 ounce package (1 cup), Chopped Macadamia Nuts

2.25 ounce package (1/2 cup), Macadamia Halves and Pieces

Affected products will have a “best before” date between November 16 and December 7, 2017. If you have the affected products, or if you have any questions about the recall in general, contact Diamond at 503-364-0399 or the company’s e-mail contact page.

If you’re curious why it is that macadamia nuts tend to have salmonella contamination, part of the reason is that they can be harvested from the ground, where dirt and (more importantly) feces are.
