BOTTULISM POISONING- HOW CRITICAL IT IS?

Food poisoning by bacteria is occurring with sickening regularity in almost all parts of the world, though such incidences are more accurately documented in the western world. Whether it is the greater immunity enjoyed by the population in poorer countries against food-borne pathogenic infection or it is lack of proper documentation very few poisoning episodes are reported from these countries. It is but natural that many wealthy countries raise their guard against food poisoning through elaborate safety regimes with high tech diagnostic facilities put in place at great cost. Recently there was a food poisoning scare due to botulism, a rare occurrence these days when canning as a food preservation method is not practiced widely. Here are a few bits of information about the dangers posed by the dreaded bacteria Clostridium botulinum, an anaerobic organism found in improperly canned food products. 

"1. Food borne botulism is caused by eating foods that contain the botulism toxin and is often associated with home-canned foods that have been improperly processed. Ingesting botulism toxin can lead to illness within a few hours- to days. Food borne botulism is often caused from home-canned foods with low acid content such as asparagus, green beans, beets and corn.
2. Wound botulism is caused by toxin produced from a wound infected with the bacterium. Wound botulism can be prevented by promptly seeking medical care for infected wounds and by not using contaminated injectable drugs.
3. Infant botulism is caused by consuming the spores of the botulinum bacteria, which then grow in the intestines and release toxin. Honey can contain spores of the botulinum bacteria and has been a source of infection for infants. Children less than 12 months old should not be fed honey. Generally, honey is safe for people one year of age and older.


The classic symptoms of botulism include double or blurred vision, drooping eyelids, slurred speech, difficulty swallowing, dry mouth, and muscle weakness. These are all symptoms of the muscle paralysis caused by the bacterial toxin. If untreated, these symptoms may progress to cause paralysis of the arms, legs, trunk and breathing muscles. In food borne botulism, symptoms generally begin 12 to 36 hours after eating a contaminated food, but they can occur as early as six hours or as late as 10 days later".

Food canning has survived in countries like the US in spite of many new technologies emerging during the last 3 decades. Canning is also practiced by many house holds under less than optimal conditions and most cases of botulism are reported from this sector. It is reported that in the US, on an average, about 145 cases of botulism occur each year but only 15 percent is due to ingestion of improper foods while 65 percent are infant botulism, rest being wound botulism. Recent studies in the US also indicate that outbreaks of food borne botulism involving two or more people occur almost every year and are usually caused by eating improperly processed home-canned foods. Utmost precaution against botulism whether food borne or from other sources is necessary to avoid unnecessary fatalities. In most developing countries more attention is focused on Clostridium tetani which causes a great number of infectious episodes through wounds, especially caused by rusted iron materials like nails, implements, knives etc.and many urban children are immunized against this infection during early days of their life.
