Interesting. The fungal production process for making citric acid leaves traces of fungal allergen in the product. Some people are sensitive enough that they suffer a reaction when consuming citric acid made this way. Depending on how common the reactions are, it sounds like there needs to be a warning on food packaging (like for peanuts) or assays developed for the allergens plus further purification of citric acid destined for human consumption.
