Depends on excessive, ever check some of the numbers from a fast food place?
McDonalds Double 1/4 pounder and crispy chicken sandwiches each have over 1,300 mg of sodium, which is over half your RDA.
The chicken was probably only 80% chicken, most fast food places are 75 or 80% chicken, the rest a laundry list of a bad chemistry expirament. Again, Mcdonalds, leaving most of the stuff off, for their crispy chicken patty. The third ingredient in the chicken is salt, it's an ingredient in the coating, and there are several other ingredients that start with sodium.
Not sure that's unexpected in some places.
