Hii Sabisha!

If you are interested in food related courses after BSc microbiology and want to make a career in this field, you can go for specialisation courses courses such as agriculture microbiology, water microbiology, pharmaceutical microbiology, industrial microbiology etc., Then you can opt for jobs in food industries, beverage industries, laboratories etc., As a researcher, food technologist, quality control inspector, pharmacologist, food technologist etc.,

Hope this helps.

Good luck!
