Meat, fish and Spices from China

Which major grocery chain sells meat, spices, fish from China? With all pesticides found on those items, how can we protect ourselves besides buying them?
Unfortunately, for restaurants you can’t tell them not to purchase food items from china because they are cheap. Once cooked and being served at their restaurants, can you tell?

To avoid pesticide residue, buy organic. Buy your meat and fish from places that clearly label their sources, or even better direct from farmers or fishermen.

Does any grocery chain not sell Chinese products? I had to mail-order Italian pine nuts as all I saw in stores were Chinese, which at best are inferior quality.
