Microbiological profile of Cronobacter sakazakii:

• Cronobacter is Gram-negative and non-spore-forming.
• Cronobacter is rod-shaped (bacillus) and motile, not a spore-forming coccus.
• Cronobacter sakazakii (formerly Enterobacter sakazakii) is a Gram-negative, motile (with peritrichous flagella), non-spore-forming, rod-shaped, facultatively anaerobic coliform bacterium of the family Enterobacteriaceae. It is a severe opportunistic pathogen causing neonatal meningitis and enterocolitis via powdered infant formula.
• It is a Gram-negative rod rather than a Gram-positive coccus.

Regulatory thresholds for patulin mycotoxin in fruit juices:

• $10\ \mu\text{g/kg}$ is the strict regulatory limit for infant foods and baby purees.
• Under Codex Alimentarius and FSSAI (Contaminants, Toxins and Residues) Regulations, the maximum permissible limit for patulin (a toxic mycotoxin produced primarily by Penicillium expansum in rotting apples) in apple juice and apple juice ingredients is $50\ \mu\text{g/kg}$ ($50\text{ ppb}$).
• $100\ \mu\text{g/kg}$ exceeds statutory safety tolerances.
• $200\ \mu\text{g/kg}$ is dangerously high and illegal under food safety standards.
