Hafnia alvei plays an active role in fermented foods, such as cheeses, kimchi and other traditional fermented dishes. Increased serum IgA and IgM have been found in chronic fatigue patients with increased intestinal permeability to Hafnia alvei, Pseudomonas aeruginosa, Morganella morganii, Proteus mirabilis, Pseudomonas putida, Citrobacter koseri, and Klebsiella pneumoniae. Hafnia alvei has the potential to decarboxylate histidine to histamine.
