Bacillus cereus is a facultatively anaerobic, endospore-forming Gram-positive rod in the family Bacillaceae, ubiquitous in soil, dust, and a wide range of foods. It is a well-established cause of foodborne illness, producing emetic (cereulide) and diarrhoeal (Hbl, Nhe) toxins, and can also cause serious non-gastrointestinal infections such as endophthalmitis, meningitis, and bacteraemia, particularly in neonates and immunocompromised patients. B. cereus is the type species of the B. cereus sensu lato group, a complex of closely related species with highly conserved chromosomes but variable plasmid content that drives differences in pathogenic potential.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
