DO NOT TRUST CHINESE FOOD PRODUCTS!
Read labels for country of origin! I do. For everything. Chinese does not make it into the shopping cart. Japanese I trust, Korean - mostly, Taiwanese - almost Chinese.
That includes all that inexpensive garlic and fish seen in stores. There is NO way to tell how it was produced.
I learned this the hard way. One day I was at a dollar store and came across some “Mens’ Multi-Vitamin” suppliment. For a buck it wasn’t bad. I started to take them but after the second day I started to feel ill. I looked at the bottle and it contained some strange sea-food ingredient that I had never hear of. NEVER AGAIN.
