Most cases of infant botulism, however, are thought to be caused by acquiring the spores from the natural environment. Clostridium botulinum is a ubiquitous soil-dwelling bacterium. Many infant botulism patients have been demonstrated to live near a construction site or an area of soil disturbance.
C. botulinum is a Gram-positive, rod-shaped, spore-forming bacterium. [1] It is an obligate anaerobe, the organism survives in an environment that lacks oxygen.However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase, which is an important antioxidant defense in nearly all cells exposed to oxygen. [7]
Food-borne botulism results, indirectly, from ingestion of food contaminated with Clostridium spores, where exposure to an anaerobic environment allows the spores to germinate, after which the bacteria can multiply and produce toxin. [143] Critically, ingestion of toxin rather than spores or vegetative bacteria causes botulism. [143]

Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores. Although now considered dated, it is still occasionally used. [citation needed]
Clostridium is a genus of anaerobic, Gram-positive bacteria.Species of Clostridium inhabit soils and the intestinal tracts of animals, including humans. [1] This genus includes several significant human pathogens, including the causative agents of botulism and tetanus.
I don't know for sure with infant botulism but in cholera the bacteria are aided in their survival and eventual colonization of the intestines by protection from stomach acid by food and Vibrio cholerae is highly susceptible to acid. Thus, spores consumed without botulism toxin can cause a botulism disease. I believe it is the same deal with ...
