Can botulism grow in canned tomatoes?
The relatively low acidity (pH 4.55) of the home-canned tomatoes and the high storage temperature may have allowed spore germination and toxin production (26 ). It has also been reported that the growth of molds may result in a higher pH, allowing C botulinum to grow (26 ).
How do you know if you’ve got botulism?

How easy is it to get botulism?
It can cause paralysis and it can be life-threatening, but it is rather rare. Botulism is usually linked with canning fruits and vegetables at home.
