Bad error if it is so. Lots of people are allergic to one of those nuts but not the other, with peanuts usually causing the most allergic reactions.

I am a bit amazed anyone could pick up that packet as shown in the photo though and buy them as almonds as you'd think you would see the difference immediately.

My concern would be for packets of almonds that might have just a few peanuts mixed in with them as that would be more likely to catch someone out.

I am finding it strange that there would only be one case of mis labelled product. That's odd. You'd think if there has been a mistake on an assembly line it would affect more than one bag.
