Why Choose Seafood 37°F (3°C) Nonreversible TTI’s?
Technology that keeps the user in mind
Easy Placement
Can be stuck directly onto seafood packaging
Inert Storage
Can be stored inert at room temperature
No Preconditioning
No prior refrigerated pre-conditioning required prior to activation
Clear activation
Activated by pushing button — ’ON’ revealed to confirm Seafood 37°F (3°C) Nonreversible TTIs correctly armed
Unambiguous temperature breach reading
Time elapsed from the breach is indicated by blue in the 2 hour window or blue in the 4 hour window
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.”
Delivery of essential cold chain data
Clear visual indication for simple decision making
- Has the cold chain been breached?
- Are products safe to use?
- Must some products be discarded?
Pure data information
- Data not dependent on ambient temperature
- Key data about location of any cold chain breach

C BOT FACTS
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.
