There has been a salmonella outbreak in the USA, possibly linked to ground turkey, which has been recalled.
I’d say play it safe, and don’t purchase/consume any for a while (that means choose a regular burger, veggie burger, or even a delicious salmon burger instead of the turkey), or if you do have to eat it, make sure it’s cooked WELL DONE! (Or, get it LOCAL, considering a mass producer that ships turkey out all over the US was likely the cause).
