On Monday I prepare a huge pot of stew and accidentally contaminate it with an enterotoxigenic Staphylococcus aureus. The pot is too big for the refrigerator so I leave it on the counter overnight. I cook it thoroughly the following day (Tuesday). What are TWO things that apply to this situation? (pick from the options 1-4) 1Thorough cooking on Tuesday will make this stew safe to eat. 2After cooking, someone eating this stew might still experience vomiting and diarrhea. 3The thorough cooking on Tuesday will kill the Staphylococcus aureus. 4The staphylococcal enterotoxin is a lipopolysaccharide and thus is not denatured by high heat.

The two things that apply to this situation ara as: Option 2- After cooking, someone eating this stew might still experience vomiting and diarrhea. Option 3- The thorough cooking on Tuesday will kill the Staphylococcus aureus. Explanation: Cooking can kill Staphylococcus aureus, but the toxins are not removed because it is heat-stable, thus it can still cause illness. Staphylococcal enterotoxin is a gastrointestinal exotoxin that has capsular polysaccharides that protect it against denaturation when exposed to high temperatures. Even though thorough boiling will kill staphylococcus aureus, it will not be able to remove the toxin, making it unsafe to eat. Staphylococcus aureus can be killed by thoroughly cooking the stew because the ideal temperature for S. aureus to grow and produce toxin is between 6°C and 46°C. Therefore, if we cook the stew above 60°C, Staphylococcus aureus will be killed.Hence correct options are 2 and 3.
