I've never had any issues with the meat department, and I tend to purchase their almost expiring marked-way-down meat. So far have purchased and greatly enjoyed cube steaks, pork tenderloin, chicken breasts/wings, Angus chuck roast, smoked salmon, brauts, sausage, ground beef and organic grass fed ground beef.
Agree if there is something weird or gross with a specific store, should be reported to the corporate. They don't mess around.
And also they revised their return policy recently in my region; it may be national. Used to be no questions asked, no receipt required - you bought an Aldi product you didn't like, you get a new product even if you used up all of it (returned the package) AND your money back. But apparently they were being robbed blind by people cheating (I imagine you could have abused the system buy things on clearance and/or return for full price and new stuff after eating most all of the product).
So now their return policy requires a receipt to get a new product and what you paid back if you're unhappy with the product. Without receipt, no cash back, just an exchange, and non-Aldi brands MUST have a receipt or no return at all.
