epidemiologist
I am an epidemiologist working for the Kansas City, Missouri Health Department. Our department is responsible for investigating and addressing public health concerns in our community. I need your help in identifying a potential source of an outbreak of foodborne illnesses.

We have identified 25 cases of foodborne illness in the past 2 weeks, all of which have been linked to eating at a local restaurant. The cases are scattered throughout the city, but they all have one thing in common: they all ate at "Tasty Bites" restaurant within the past 72 hours before the onset of symptoms. The symptoms include diarrhea, vomiting, and stomach cramps.

I need your help in analyzing the data and identifying a potential source of the outbreak. I have attached the case data below:

| Case # | Age | Sex | Date of Onset | Date of Meal at Tasty Bites |
| --- | --- | --- | --- | --- |
| 1 | 32 | M | 2/10 | 2/8 |
| 2 | 45 | F | 2/11 | 2/9 |
| 3 | 28 | M | 2/12 | 2/10 |
| 4 | 19 | F | 2/13 | 2/11 |
| 5 | 50 | M | 2/14 | 2/12 |
| ... | ... | ... | ... | ... |

I have also attached the menu items that the cases reported eating:

| Case # | Menu Item |
| --- | --- |
| 1 | Chicken Fajitas |
| 2 | Veggie Burger |
| 3 | Chicken Quesadilla |
| 4 | Grilled Chicken Sandwich |
| 5 | Beef Tacos |
| ... | ... |

Based on the data, what is the most likely source of the outbreak?[/INST]
