No, it’s not easy to pop hot just from eating a dish with poppy seeds and it hasn’t been for a long time. The trace amounts aren’t nearly enough to reach the minimum threshold.
I would be 100% willing to believe hospital used substandard or defective tests, that she was on another legally prescribed medication that causes false positives, or even that the hospital administered opiates themselves, and through negligence and incompetece, forgot to put it in her chart.
But whenever someone says they ate a poppy seed muffin or salad, and that’s the only explanation they have, I’m immediately leaning towards actual opiates being the culprit.
Not saying it’s impossible these days, I’m saying it’s the least likely possible answer between those two options.
That said, this is the American healthcare system, so my money is on hospital error of some kind.
