Case Study Assignment – HOTL1221

Maria was very pleased and delighted with the group of students in HOTL1221 because they followed the TLP, worked on the Food Safety Online Portal, and handed in their assignments on time. Maria has planned a Surprise Spooktacular Halloween Dinner Party for the students. The menu items for this party included pizza, chicken wings, perogies, and pumpkin tarts.

Grocery list items to purchase:

  • chicken, vegetables, cheese, pepperoni, tomato sauce , sour cream, hot sauce, butter, pumpkin filling


To assist Maria with this party’s preparation and to buy supplies, she invited her good friend, “Witchy Poo” and her cat “Bookie” to help.


Once Maria and Witchy Poo returned from purchasing groceries from the neighbor’s, they noticed that Bookie must have been walking over the kitchen counter because there were traces of cat hair. When looking for Bookie, they saw that Bookie fell asleep on the cutting board. Maria said, “Silly Kitty” and moved Bookie on to a chair. Maria started to take the raw chicken, vegetables, cheese, and all the other items out of the bag and place them on the counter to prep the dinner. Maria noticed that the can of tomato sauce was severely dented and bulging but decided to use it because it was inside that matter.


At this time, Witchy Poo took the cutting board from the counter and began cutting the raw chicken into pieces with the knife that was in the sink. Suddenly, Witchy Poo got an itch and scratched her head and said, maybe I should wear my hair up? Maria said, no worries, you have such beautiful long black hair you don’t want to ruin it for the party. “You’re right,” Witchy Poo said and continued cutting the raw chicken.


Witchy Poo finished cutting the raw chicken on the cutting board; she started to cut all the pizza ingredients with the same knife, vegetables, mozzarella cheese, and pepperoni. To save time on the preparation, she didn’t wash the vegetable because they looked clean. After Witchy Poo finished cutting the ingredients and was ready to bake the pizza, she washed her hands and asked Maria, do you have any paper towels to dry my hands, but Maria said no, sorry I ran out. Witchy Poo said that’s okay; I’ll wipe in on my dress.


During this time, Maria was rolling the dough for the perogies and sneezed. Oh my, Maria said. I sure hope I’m not catching a cold and continued rolling the dough. Witchy Poo asked Maria, “Can I help you make the delicious potato and cheese filling for the perogies? Maria replied, I made it 7 hours ago, and it’s been sitting on the counter, ready for me to start filling the dough. Witchy Poo said that was excellent planning on your part Maria.


After making the Surprise Spooktacular Halloween Dinner Party’s food, Maria and Witchy Poo were exhausted. They decided to cover all the food in napkins and leave on the counter overnight and finish the clean up in the morning.
