Real bummer! We just got back into raising chickens, and we have a ton of kale and leaf lettuce ready to harvest, and now that the wife has been diagnosed with blood cancer she can't have any of it, and can't be near the chickens.
Apparently the leaf veggies are more likely to have bacteria, same with the chickens. She's not supposed to have any fruits or veggies that can't be peeled or cooked to a bacteria killing temperature.
Her white blood cell count is so low that getting any kind of "ill" would be dangerous as her body has basically no way to fight it.
