Bismihi ta'āla
Wherever you are, and whichever country you may be in, if its non-Muslim country, or even in some cases Muslim country, it is important to check and verify the ingredients of it is not made by Muslim manufacturer.
1. If it does not have anything haram, and you have assurance that there is no shar'i issue with it, you can consider it halal.
2. Ihtiyat is always good. If you are uncomfortable about a certain product, being halal or haram, best to avoid.
3. It is not you absolute duty to investigate, and pry into everything, but you cannot easily turn away from it as well.
Try to stick with things you know are made in Muslim country. Try to find alternatives, and remember that with the difficulty you endure, you will be rewarded more.
And Allah knows best
