I want to share a method that it seems few are taking advantage of in purchasing the ServSafe study material. Take a look at my "store page" for a selection of ServSafe books that are quite a bit cheaper than purchasing new. Currently the exams are written from the 6th edition ServSafe, but the 5th edition and even the 4th edition would easily get you through the exam. (.99 cents) instead of ($50 Dollars). I hope that helps.
Answer to one of the questions on the exam,.... all equipment must be NSF certified or UL certified meeting NSF standards. Having said that, please see my "store page" for NSF authorized food industry thermometers and equipment. I'll add more options as I find them.
I've been meaning to provide good study information on this site for a while now, and I am getting closer to doing it.
