The CORE Outbreak Investigation Table is a list of outbreak and adverse event investigations primarily being managed by FDA’s CORE Response Teams. The investigations are in a variety of stages, meaning that some outbreaks have limited information, and others may be near completion. The table will be updated weekly.
This week's updates are:
For the outbreak of Clostridium botulinum (ref #1383) linked to a Nara Organics Whole Milk Powdered Infant Formula, FDA has initiated sampling.
For the outbreak of Salmonella Enteritidis (ref #1378) linked to a not yet identified product, the case count has increased from 68 to 70.
