On Sunday night, John Oliver simply scoffed at that idea. To kick off the latest episode of “Last Week Tonight,” Oliver zeroed in on the cyclospora outbreak, which is giving consumers explosive diarrhea. “Yeah, the best advice they have for you right now is to basically play lettuce detective at every restaurant,” Oliver said, stifling a laugh. While Oliver scoffed at the “notes app non-apology,” he did give Taco Bell credit for at least proactively addressing the issue, saying it’s more than the Trump administration has done. “Last Week Tonight” airs Sundays at 11 p.m.
