Kind of, especially the rural areas with less strict regulations.
Looking at China today reminds me of my life back in Taiwan 10+ years ago. Government regulations exist, but a lot of evil inner loops make these regulations untrustworthy. You hear news reports of cancer-related additives being mixed with various food, from manufacturers of all sizes, all the time. It has gotten much better now, but it's still not to say that these problems have been completely eliminated in Taiwan...
Also, since Taiwan now imports a lot of food from other places such as mainland China, a lot of problems, such as the the milk powder incident, is still quite influential at Taiwan.
