Most supermarket meat is injected with stuff to keep it looking fresh- maybe there are carbs in that.
The label states “New Zealand Beef,Processed And Packaged In The US.”
I’d guess this takes place during a specific stage of “processing” so that listing the ingredients is not required.
I do see an 800 number- why not call and ask?
Most good has trace carbs and the fat content most likely is based off the animals diet being controlled and also how it’s cut. The label is just an estimate, for the most accurate nutrition facts stick with ground meat.
