Association between traditional fermented milk (mursik) consumption and oesophageal carcinoma among patients presenting to two referral hospitals in Nandi County, Kenya: A case-control study

In this study setting, mursik consumption was strongly associated with OC independent of other risk factors. This association registered a high PAF suggesting that up to 65% of OC in the population could be prevented if mursik was not consumed. This finding calls for safe, community-owned alternatives for fermenting milk in order to mitigate the risk of OC in this population.
