Best C bot prevention

Best C Bot prevention tool for low oxygen packaging that keep seafood products fresh

“A control strategy is now included on the use of Time Temperature Indicators or TTIs on reduced oxygen packages where maintaining the product below 38 degrees Fahrenheit is the only control to prevent nonproteolytic C. botulinum toxin formation.”

FDA Fish and Fishery Products Hazards and Controls Guidance, 4th Edition

Delivery of essential cold chain data

Clear visual indication for simple decision making

  •  Has the cold chain been breached?
  •  Are products safe to use?

C bot type E and non-proteolytic types B and F are psychrotrophic and can grow and produce toxin at temperatures as low as 3°C (37°F). Other strains of C bot (type A and proteolytic types B and F) can grow and produce toxin at temperatures slightly above 10°C (50°F).

The aim of Timestrip® Seafood 3°C TTIs is to provide seafood processors and transporters with clear, unambiguous data as to whether the handling of any individual seafood product, that has or is being processed, adhered to C Bot prevention standards around cold chain management.
