Antibacterial properties of green tea polyphenols and EGCg

Green tea is often served at sushi restaurants not just for healthy drink, but also known to reduce risk of food poisoning. Some of the most deadly food poisoning bacteria are very sensitive to green tea polyphenols (catechins).  C. botulinum is commonly found in soil, yet most notable botulism cases come from improperly canned foods.  In order to destroy C. botulinum spores, you must cook at 120C for more than 4 minutes.  In green tea drinks due to its antimicrobial property 85C for 30 minutes can almost completely destroy.  In intestinal tract it is reported that less than 100ppm of green tea catechins is required to achieve MIC for C. botulinum. Hara et. al. (*1) shows that effects of green tea catechins (green tea polyphenols) on human intestinal bacteria.  Lactobacillus acidophilus and Bifidobacterium bifidum generally considered as beneficial bacteria showed significantly greater minimum inhibitory concentration (MIC) to catechins while   Clostridium and Staphylococcus that c
