I apologize for my poor English. I found English to be very difficult for me, though I was trying my best.
First we talk about additives, the food safety laws in Taiwan are outdated and have a lot of loopholes. So some harmful additives that are forbidden in most of the countries might be legally used in Taiwan.
You should also be really worrying about the additives approved by most of the countries in Taiwan. Why? It's because the standard amount of those additives in Taiwan may have exceeded the international standard amount way too much.
So don't just let your guard down when you find out the additives of the food you pick are approved by the international standard, since the amount of those additives may still exceed the international standard. What's even worse is that some of the additives are not even legal to be used in Taiwan but you can still find reports about people putting illegal additives in foods and selling them.
Now we talk about the food hygiene, when you eat out in Taiwan, you can't really expect the food to be clean. I remember eating in a small noodle restaurant and I had an urge to use the restroom (by the way, many of small restaurants do not have restrooms available, they are only for employees), so I asked one of the employees if I could use it.
And yes I was allowed to use the restroom but I was disgusted as the moment I walked in, there was a table in the restroom and on the table were the pots filled with soup(without pot lids) and the vegetables, I also noticed there were buckets filled with their sauces on the floor. I quickly used the restroom and left.
After the incident, I seldom ate out. But when I have to eat in a small noodle restaurant, I always ask if I can use their restrooms. The other big problem of most small Taiwanese restaurants is that their kitchens are outside, which also means flies, mouses, and cockroaches can easily touch your food.
I can't assure you bigger restaurants have better hygiene since most of the Taiwanese vendors don't really care about it and the department of health in Taiwan is tremendously inefficient.
Surprisingly, Taiwanese don't seem to care about the food safety. They may get angry when a food scandal first spread over Taiwan, but after like three weeks, they either stop caring about it or just simply forget the whole incident.
A lot of Taiwanese also prefer foods that are yummy and cheap and large, I don't exactly know why but it's just a trend in Taiwan. So it's easy to imagine how vendors balance these three things in their food. The manufacturers that make processed food that contains harmful additives just need to re-manufacture their products and repackage them(or advertise their improvements), and then they will be fine. People will still buy their products. Also the food safety laws barely punish those manufacturers and will not be able to protect customers from getting those potentially toxic food. At this point, I think you're starting to understand why the food safety in Taiwan is horrendous.
If you often read topics or watch videos about Taiwan food safety on the internet, you may notice there's a phenomenon in some comment sections in which some Taiwanese start changing the subject of the topic/the video and scolding that the food safety in Western countries are no better and every country has the same severe food safety situation like Taiwan.
Another interesting phenomenon I've noticed is that if a person suggests people should avoid eating in night markets due to the very worrying food safety and hygiene, people would scold the person for being haughty and arrogant or even see the person as rich.
But there's more!! When someone complains or gets depressed about the food safety in Taiwan, many Taiwanese will respond with something like "We have eaten a lot of harmful things before, and yet we are still alive, don't overthink it." or "I think those unscrupulous vendors have learned their lesson, so don't worry about the food safety.", or "You are lucky compared to those starving people, they don't even have food to eat and you're here not knowing if you should eat your food just because of its food safety?". It is more common to hear the first and the second comment during the food safety/scandal related conversations.
If you think eating in a expensive restaurant in Taiwan guarantees you a safe meal, you might be disappointed in what I'm about to tell you. Even high-end steakhouses in Taiwan served customers restructured meat.
Studies show that restructured meat should be cooked well-done(the doneness), otherwise you may likely get food poisoning. It means you may die from eating restructured meat. The thing about those Taiwanese steakhouses is they won't tell customers about the restructured meat and still ask customers how they would like their steaks, causing people who like their steaks medium-well(or more rare) potentially get food poisoning without knowing it.
There was a time when I didn't know about restructured meat, I sometimes went to those "affordable" steakhouses, and there were multiple times I felt like I got headaches after eating their steaks that were cooked medium-well. It goes without saying that most of the steakhouses in Taiwan are still using restructured meat as steaks, especially for those "affordable" steakhouses. And yeah, following the logic, the pork slices and beef slices in Taiwanese hot pot restaurants are also most likely restructured meat, please think twice before eating any meat products in restaurants in Taiwan.
You may want to cook for yourself after reading this post, but what you should beware of is the condiments and the seasonings made in Taiwan, there are reports of safety issues with some condiments and seasonings made in Taiwan(also link down below).
