During the summer, the air conditioning of your house stopped working and the temperature i: s 95 °f. how long can slices of bread sit on the counter before it becomes unsafe to eat due to contamination with staphylococcus aureus given the following conditions were used for the preparation of shelf-stable bread according to military specifications mil-b-44360a: with no glycerol.1 (10 points) with 6.3% glycerol but not equilibrated with a salt solution. (5 points) with 6.3% glycerol, same water activity as part 2, and equilibrated with a salt solution. (5 points) with 6.3% glycerol, water activity of 0.836, and equilibrated with a salt solution. (5 points) 1. 2. 3. 4. assume the following: you will eat two slices of bread for breakfast (each slice weighs 50 g). there are 10 organisms of s. aureus per m3 in air.2 1% of the airborne organisms land on a slice of bread per hour infective dose of s. aureus is 105 organisms (colony forming units or cfu) in humans.3 changes in water activity are negligible over the temperature of measurement and temperature of the room. note: explicitly state any other assumptions that you make. show all your work (including any code/spreadsheet used for calculations). include the following sections in your answers for each question: » known unknowin * relevant concept(s) ° assumption(s) » solution » conclusion hint: refer to table 2 of the paper by feeherry et al. for necessary data. log is base 10 in the logistic model and in the plots
