Delhaize chicken stinking?

Hi,

I am buying regularly food at Delhaize Moliere and on many occasions I found that some packed meat products - especialy BIO chickeen for example and last time sole fish - stank very much and have obviously gone bad. I had to therefore throw them away. The chicken was much before the expiry date and I never had similar problems with other products from other shops.

Did any of you had similar experience?
