Which botulinum type is associated with growth and toxin formation at lower temperatures?

• A. Type A
• B. Type B
• C. Type C
• D. Type E

Answer: (D)

Some botulinum types are only able to grow and produce toxin in warmer conditions, but one type can multiply even when foods are refrigerated. This type is adapted to cold environments and can grow and form toxin at temperatures near typical fridge temps, which is why it’s often linked to refrigerated fish and other seafood. The other types generally require warmer temperatures and don’t reliably produce toxin in the cold. So, the type associated with growth and toxin formation at lower temperatures is Type E.
