Verified step by step guidance1
Step 1: Understand the question is asking to identify a common and serious foodborne pathogen from a list of microorganisms.
Step 2: Review the characteristics of each microorganism listed: Bacillus subtilis is generally non-pathogenic and used as a model organism; Streptococcus pneumoniae is primarily a respiratory pathogen, not typically foodborne; Nitrosomonas europaea is involved in nitrogen cycling and not associated with foodborne illness.
Step 3: Recognize that Salmonella enterica is a well-known foodborne pathogen responsible for causing salmonellosis, a common and serious foodborne illness.
Step 4: Conclude that among the options, Salmonella enterica is the correct answer because it is both common and serious in the context of foodborne diseases.
Step 5: Remember that identifying pathogens involves understanding their typical habitats, modes of transmission, and disease associations.
