There are a bunch of resources on the OSHA.gov website that you can use to check if the company you work for or are planning to work for have violated safety and health regulations. Go to OSHA's website and look under “Help and Resources” and then “establishment search” (https://www.osha.gov/pls/imis/establishment.html).
Under Type you can see if the company has any fatalities or catastrophes “Fat/cat” and you can review other safety and health complaints there.
I read this article: https://www.wsws.org/en/articles/2022/10/05/uhvk-o05.html
about Casen Garcia who died of electrocution at a Tyson meat packaging plant which prompted me to see how many fatalities have been listed at Tyson.
