Is it possible to prevent botulism?
Yes, botulism prevention is possible. Food-borne botulism has often come from improperly prepared home canned foods such as asparagus, green beans, beets, and corn. However, there have been outbreaks of botulism from more unusual sources such as chopped garlic in oil, agave nectar, chili peppers, broccoli, tomatoes, tomato sauce, improperly handled baked potatoes wrapped in aluminum foil, and home canned or fermented fish. People who do home canning should follow strict hygienic procedures to prevent or kill Clostridium bacteria, their spores, and neutralize its neurotoxin. Oils that are infused with garlic or herbs should be refrigerated. Potatoes that have been baked while wrapped in aluminum foil should be kept hot until served or refrigerated. Bacon should be cooked well since bacon preservatives (salts), which inhibit clostridial spores, have been reduced. Because botulism neurotoxin is destroyed by high temperatures (85 C for five minutes), people who eat home canned foods should consider boiling the food for 10 minutes before eating it to help ensure that the food is safe to consume. Other canned foods that are commercially produced and are bulging (the can is deformed and looks like it is over-pressurized) or if abnormal-smelling preserved foods are found, they should be discarded. Do not taste-test them or attempt to boil the food!
Because honey can contain spores of Clostridium botulinum and this has been a source of infection for infants, children less than 12 months of age should not be fed honey. Honey is relatively safe for people 1 year of age and older.
The FDA publishes recall lists of commercially produced foods that may contain botulinum toxin. One large recall was Castleberry Food Company's hot dog chili sauces and dog food in 2007. In October 2009, Plumb Organics issued a recall of baby food (apple and carrot preparations) that was thought to be tainted with botulinum toxin. In October 2015, Seaquest Seafood Corp., in California, recalled its Sunrise brand marinated fish. Several types were recalled by the FDA due to potential Clostridium botulinum contamination. Several other FDA recalls have occurred in 2015, including one in Ohio due to home canned potatoes that killed one and sickened about 50-60 others. Avoiding such potential sources of toxin can prevent botulism.
Vaccine development for the major human types of botulism neurotoxin is currently being investigated, but there is no vaccine commercially available or approved for public use by the FDA. However, in the United States, an investigational pentavalent (against neurotoxins A, B, C, D, and E) botulinum toxoid vaccine can be distributed by the CDC for laboratory workers at high risk of exposure to botulinum toxin and by the military for protection of troops against attack. Unfortunately, it takes several months to induce immunity. In 2009, a research finding with molecules that mimic botulism toxin binding sites was described that may provide another method to block toxin from binding to nerve tissues, but this approach is only in the research phase of development.
The herb milk thistle has been suggested by alternative medicine proponents (mainly in Europe) to treat food poisoning (especially mushroom poisoning) and to help detoxify the liver. There are no good data on its use in preventing or treating botulism.
