Trader Joe's will give up single-ingredient items from China, such as garlic and frozen spinach, by April 1. Products that include ingredients from China will still be sold. "We feel confident that all of our products from China meet the same high quality standards that we set for all of our products," spokeswoman Alison Mochizuki said in a statement. "However, our customers have voiced their concerns about products from this region and we have listened. We will continue to source products from other regions until our customers feel as confident as we do about the quality and safety of Chinese products."
