Eat locally-produced foods. Problem solved.
I don’t think eating locally produced food is an end all to the problem. What if one of the ingredients used in the food comes from China.
All the pet foods were made in either Canada or the US, but the problem arose when an ingredient was imported from China (in the pet food case...rice powder, and wheat gluten.)
Even if I were to go to my local supermarket bakery, I have no idea where their ingredients are bought. The food may be produced locally, but are the ingredients imported...that’s the big question.
Since the article says that Vitamin C is produced in China, then I guess I have to be “suspicious” of any food that contains extra Vitamin C.
