According to MiceTimes of Asia (great name) there have been 90 illnesses and nine deaths in 2017 from foodborne botulism in Ukraine this year. Seems like a lot. Home canned foods and dried fish have been linked to many of the illnesses. Dried fish and botulism seem to go together. Five bot cases in Germany and Spain were linked to dried fish in 2016.
To prevent botulism, you must carefully follow the canning of vegetables, fruits, meat, fish and mushrooms. Before the use of canned foods should be warmed to a temperature of 100°C for 30 minutes to destroy botulinum toxin.
In no case can not eat canned meat and fish, if the iron Bank is inflated or deformed.
