Poop experts!!

Is this what mucusy poop looks like? My daughter is 10 months old and has multiple food allergies. We’ve already had her tested and she tested positive for peanut, tree nut, and milk. But she doesn’t eat any of that. Her eczema flares up when she has foods high in salicylates (like sweet potatoes, spinach, strawberries, also ibuprofen) but we’ve been avoiding those as well. She’s on Elecare formula and only eats things like carrots, brown rice pasta, arugula, kale, chicken, green beans, all organic and made fresh. She doesn’t eat any of the top 8 allergens. I fed her Brussels sprouts and garlic this morning and I don’t usually pay attention to her poops but I noticed it’s pretty green and stringy? I’m going crazy trying to find foods for her to eat already could this signify an allergy?
