I'm trying to understand whether or not there are leniencies regarding kosher certification in countries where it's uncommon. I am aware that in many parts of the world there are almost zero products with hechshers, as well as a lack of comprehensive kosher lists.
One website I found on kosher travel in Europe seems to suggest that (i.e. for pas palter bread) one only needs to check the ingredients to confirm the absence of ingredients known to be non-kosher, such as certain emulsifiers. I then found a source by the Noda B'Yehuda that seems to say that even if a not kosher ingredient is present, it is typically nullified.
Coming from the US, it seems strange to me that it would be acceptable to just go buy bread without a hechsher and check the ingredients. Can anyone confirm that this is the case, or show sources that prove I'm not crazy?
