Ukrainian producers do not necessarily have to follow all the same animal welfare and environmental production standards as EU farmers. As you said, they may also use certain pesticides that are not approved for use in the EU.
I should also mention that Poland introduced an embargo on certain Ukrainian agricultural products despite opposition from Brussels. We are still an independent country, and we will protect our farmers and our food standards. As a vegan, I also want to know that animals are treated as well as possible, but that is my personal point of view.



I am definitely not an expert on this topic, so I recommend looking up the sources yourself. :)
