Would leaves have allergen?
« on: May 21, 2019, 03:51:37 PM »

A supermarket chain in Chiangmai, Thailand, is doing its part to stem the tide of single-use plastics flooding into the ocean.

While most supermarkets bundle their strawberries in plastic boxes, their corn in plastic shrink wrap and their mushrooms in plastic produce bags, this grocer has come up with an innovative, eco-friendly solution.


Would this be a risk to people with an allergy to banana?

Interesting question.  My first thought without doing any research would be no.  I could see it being problematic more so for those allergic to pollen from the particular plant (do banana plants have pollen that people are allergic to?) or even those allergic to mold that grows on the leaves.  I do, however, assume that anyone highly sensitive to bananas would want to avoid banana leaves and might avoid many fruits and vegetables from markets where they could have come into contact with bananas, anyway, if washing wasn't enough to prevent cross-contact reactions.

Trying to think about my own allergies... I am extremely allergic to grass - as in systemic reaction requiring epi to grass SPT.  If I dropped a piece of fruit on the grass would I eat it after washing?  Most likely.  If I got something wrapped in peanut plant leaves, though, I don't think I'd touch it with a ten-foot pole.  I can't explain my reasoning.
DS - peanut, tree nut, milk, eggs, corn, soy, several meds, many environmentals. Finally back on Xolair!
DD - mystery anaphylaxis, shellfish.
DH - banana/avocado, aspirin.  Asthma.
Me - peanut, tree nut, shellfish, banana/avocado/latex,  some meds.

My thoughts echo Rebekah here.  As another example: people with tree nut allergies can safely be around and eat off of walnut wood products or flooring, but I would never have it in my house just for the eerie closeness.  Or how people with egg allergy can eat chicken.  They are very different products.  Whilst some cross reactivity might happen, I think it would be low risk in general.

I am far more concerned about printer paper and paper plates made from wheat, cling wrap made from milk, biodegradable bags made from corn, and goodness knows what else other places are creating that aren't required to be labelled as containing major allergens.  (I know corn isn't a priority allergen.)  Give me all the banana leaf packaging!
