I bought sliced Applegate smoked chicken on the 16th. Do we think it is still good today? Thanks!

employ the sniff test. if it smells like anything other than inocuous smoked chicken, throw it out. you can also try the slime test; if it feels slimy or slippery, toss it. otherwise, since it's only been a few days, it's probably fine, especially if it's been kept refrigerated.
