That is one of the molds that can be found in homes, that's why I asked if your house had been checked for it.
Just out of curiosity, why are you focusing on the mold, when there are so many other foods listed on his IgG test? Does the doctor think the mold is the worst? Or that all the other foods are contaminated by the mold? Was there any mention of a rotation diet to let you include some of the "low" foods in the rotation?
Did the test show any foods as safe? Or did they only give you the list of reactive foods?
From my son's list, these are foods that don't appear on your list, so may be safe to try (I was scrolling up/down so hopefully I didn't miss any):
starches/grains: tapioca, buckwheat, millet, rice
veggies: white potato, sweet potato, artichoke, black-eyed peas, celery, eggplant, sweet green pepper, lettuce, chickpea, brussel sprouts, regular cabbage (did they only test chinese cabbage?), lentil, lima bean, beet, cucumber, zucchini/yellow squash
fruits: tomato, mango, papaya, strawberry, apple, pear, cherry, plum, honeydew melon, watermelon
meats: cod, lamb, duck, turkey
seasonings/herbs: parsley, maple syrup, cane sugar, beet sugar, mustard, cinnamon
Does that at least give you a starting point? When we first did our ALCAT test, we got similar results, but they gave us a list of "green/safe" foods and a rotation, then as you added things back in, you put them into the rotation. For instance my DS was "mild" to pork. If he only has it once every 4 days, he's fine with it. If he has a ton of it on that day or more often that that, he'll react. We've been rotating foods since June '08 and are adding foods back in. Have you done any stool testing or anything to find out why he's reacting to so many things? It didn't seem like we were adding back anything until our osteo ordered a Genova stool test, and we found out he lacked some things (like any beneficial bacteria). Since getting on enzymes and the right probiotics, we seem to be adding foods left and right.
