But with Trump reducing the number of #OSHA inspections and cutting inspectors to an all-time low, will that trend continue?

RFK Jr., once poisoned by mercury, is silent as EPA weakens rules against it The HHS secretary has fought mercury pollution for years. He’s now in an administration that wants to make it easier for industries to dump it into the air

Mercury is a potent neurotoxin that contaminates people when air pollution settles on rivers and streams and gets into the fish we eat. Current Health Secretary RFK jr once had mercury poisoning from eating too much tuna, but has been silent these rollbacks

The USDA announced it would extend faster line speed waivers to meat processors, citing "extensive research" that had not confirmed a "direct link" to worker injuries. In fact, there were only 2 studies (meat & poultry) both of which found job-specific line speed did increase the risk.
