Meats in the baby food stage 1 ?

My husband and I went to wal*mart yesterday to buy our 4 and a half month old some baby foods [ pediatrician gave us the go ahead at her 4 month check up ], anyways, & I noticed there were 2 jars...1 said chicken w/ chicken broth stage 1, and turkey w/ turkey broth stage 1. I didnt know they made meats in the stage 1 ?! Did they just start doing this ?! & have any of you gave your baby the meats in stage 1? I didnt buy any of them, just fruits & veggies...but i mean obviously its okay to give, if its in stage one ? thanks in advance.
