Overview of histamine‐producing bacteria as relevant biological hazards based on the selection against two criteria: (1) evidence of causing human illness (histamine intoxication) associated with fresh fishery products and (2) evidence of biogenic amines production in fresh fishery products within the range −3°C to 7°C

Hazards included in the assessment		Hazards excluded from the assessment
Hazard	Assessment approach	Hazard	Reason for exclusion
Enterobacter spp.a	Appraisal of bibliographic data	Aeromonas spp.	No evidence of human illness
Morganella spp.	Simulation applying predictive models for M. psychrotolerans	Citrobacter spp.	No evidence of human illness
Photobacterium spp.	Appraisal of bibliographic data	Cl. perfringens	No evidence of human illness
		Hafnia alvei	Weak evidence of human illness but no evidence of biogenic amine production
		Klebsiella spp.	Evidence of human illness but no evidence of biogenic amine production
		Proteus spp.	No evidence of human illness
		Providencia spp.	No evidence of human illness
		Pseudomonas spp.	No evidence of human illness
		Raoultella spp.	Evidence of human illness but no evidence of biogenic amine production
		Serratia spp.	Weak evidence of human illness but no evidence of biogenic amine production
		Staphylococcus spp.	Weak evidence of human illness but no evidence of biogenic amine production
		Vibrio spp.	No evidence of human illness

^aFor consistency among information sources, Enterobacter spp. were considered according to the standing classification at the time of publishing of the screened articles.
