C. botulinum: Spores and vegetative cells are likely to survive the cold-smoking process, but growth is unlikely except in the case of vacuum or modified atmosphere-packed products, as C. botulinum is an obligate anaerobe.
Even in the case of vacuum packed and modified atmosphere-packed products, salt concentrations (typically in the order of 5% or higher) are likely to inhibit growth and toxin production by non-proteolytic (Group II and III) types [9,55]. There have been no recorded cases of botulism in Australia in the period 1991–2003 [56].
