You left a carton of orange juice on your counter for 3days. When you taste it, it is very
bubbly (as though it was carbonated), and it tastes more bitterthan usual. (Note: acids taste
bitter). What do you think could have happened? (Note: you can’tjust say that bacteria grew—
you must explain how the growth of the bacteria resulted in thechanges in the orange juice.)

Based on what you now know about the presence of bacteria onchicken and beef, why is it a
good idea to use separate chopping boards for meat and forvegetables?
