During a multistate outbreak of Salmonella linked to a processed snack, which action would the CDC most likely take that differs from the actions of FDA or FSIS?

• A. Perform routine on-site inspections of manufacturing lines and certify corrective actions for the snack plant before product releases resume, tasks that are primarily the responsibility of FDA or FSIS.
• B. Coordinate case finding and epidemiologic interviews across states, analyze surveillance and genetic sequencing data (e.g., PulseNet), and publish public health guidance while collaborating with FDA or FSIS that handle recalls and regulatory inspections.
• C. Set legally binding maximum allowable Salmonella levels for finished snack products and issue final regulatory orders mandating plant shutdowns, authority granted to the CDC during outbreaks.
• D. Directly collect and test all company field samples for pesticide residues and enforce tolerance exceedances through federal fines and product seizures independent of other agencies.
