| 0:00.0 | Nick Florco doesn't want to brag or anything, but it was more than a year ago that he wrote an article that has come to seem prescient. |
| 0:14.7 | Its title was, Now is Not the Time to Eat Bagged Lettuce. |
| 0:22.6 | Nick wrote this way before the multistate outbreak of cyclospora, a parasite that is associated with explosive diarrhea. |
| 0:31.6 | But now that this outbreak is here, Nick's ready. |
| 0:35.5 | So tell me what your fridge looks like right now. |
| 0:38.1 | I have a wedding coming up in a week and a half. |
| 0:42.6 | So you're living on cans. |

| 1:36.7 | tough, maybe even impossible to wash off. And like Nick said, you can ingest this parasite |
| 1:44.1 | and not feel the impact for weeks. |
| 1:48.1 | Can I tell you a story about me? Yeah, of course. I love kale, but bagged kale. I love bagged kale. |
| 1:56.1 | It's on my list every week. The little bag says it is triple washed. I trust the bag. I pour it from the bag |
| 2:04.3 | into a bowl. And at least once a week I eat that salad. Is that a good idea right now? |
| 2:11.4 | No, it is not a good idea. I feel like the kale is hardier. Maybe it's somehow rejecting |
