[Infant botulism was confirmed in Ehime Prefecture]
Summary
The third infant botulism case in Japan involved a four-month-old boy. *Clostridium botulinum* type A was found in his feces and honey, confirming infant botulism.
Area of Science:
- Pediatrics
- Infectious Diseases
- Toxicology
Background:
- Infant botulism is a rare but serious neuroparalytic illness caused by *Clostridium botulinum* spores.
- Early diagnosis and treatment are crucial for favorable outcomes in affected infants.
- Environmental sources, including food products, are potential reservoirs for *Clostridium botulinum*.
Observation:
- A four-month-old infant boy presented with sudden onset of poor suckling, constipation, and generalized muscle weakness (hypotonicity).
- The infant had a history of normal growth and development until 19 weeks of age.
- Daily consumption of fruit juice and honey was reported for the infant.
Findings:
- Bacteriological examination of fecal samples identified *Clostridium botulinum* type A.
- Analysis of honey consumed by the infant also yielded *Clostridium botulinum* type A.
- Type A botulinum toxin was detected in the infant's feces, but not in his serum.
Implications:
- This case highlights honey as a potential source of *Clostridium botulinum* type A in infant botulism.
- Reinforces the importance of considering *Clostridium botulinum* type A in the differential diagnosis of infantile hypotonia and feeding difficulties.
- Suggests the need for continued vigilance and public health awareness regarding potential foodborne risks for infants.
