In Scenario 1, possible sources of food-borne illness include improperly stored or handled foods, cross-contamination, and unsanitary food preparation areas. Jeremiah's day may have involved touching raw meats, contaminated surfaces, or consuming improperly cooked or stored foods. To reduce risk, he could have washed hands frequently, kept raw and cooked foods separate, and ensured foods were cooked to safe temperatures.
Steak is safe to be pink in the middle because the high temperature used during cooking kills bacteria on its surface, and the internal temperature may be sufficient to eliminate pathogens. In contrast, hamburgers, which are ground meat, pose higher risks if undercooked because bacteria can be mixed throughout the meat during grinding. Thus, hamburgers should be cooked thoroughly to avoid food-borne illness.

Food-borne illnesses are caused by consuming contaminated foods or beverages containing harmful microorganisms such as bacteria, viruses, parasites, or toxins. In Scenario 1, potential sources include improper hand hygiene, cross-contamination between raw and cooked foods, inadequate cooking temperatures, and poor sanitation in food handling. These factors increase the likelihood of pathogenic bacteria like Salmonella, E. coli, or Listeria contaminating food. For example, if Jeremiah failed to wash his hands after handling raw chicken or used unclean utensils, he risked introducing bacteria that could cause illness. Additionally, consuming foods that were left out at unsafe temperatures for extended periods can foster bacterial growth. To prevent food-borne illnesses, proper food handling practices—such as thorough cooking, refrigeration, and personal hygiene—are crucial. Jeremiah could have washed his hands before eating, ensured raw foods were kept separate from ready-to-eat items, and cooked meats to safe internal temperatures to minimize risk.
Regarding cooking safety, it is generally safe for steak to be pink in the middle because the surface of whole cuts of meat is exposed to high temperatures during cooking, killing surface bacteria. The interior may remain pink if the internal temperature reaches a level sufficient to kill pathogens (at least 145°F or 63°C for beef), which is still considered safe. However, with ground beef, the bacteria may be mixed throughout the meat during grinding, making it more susceptible to contamination. As a result, ground beef must be cooked thoroughly—an internal temperature of 160°F or 71°C—to ensure safety. Under cooking a hamburger, which is ground meat, can leave bacteria alive inside, increasing the risk of food-borne illness.
Scenario 2write at least 50-word responses to each of the following questions
This scenario examines how improper handling and storage of food can lead to food-borne illnesses, emphasizing the importance of correct cooking, cooling, and storage practices. The focus is on understanding incubation periods, microorganisms involved, and food safety steps to prevent illness.

In Scenario 2, the food-borne illness appears to have been caused by improper handling of the lasagna, particularly insufficient cooling and storage. To prevent such illnesses, food should be cooled rapidly within two hours after cooking, ideally in shallow containers to facilitate heat loss. Martha could have sped up the cooling process by dividing the hot lasagna into smaller portions, using an ice bath, or employing refrigerated blast chillers. Proper refrigeration is critical to prevent bacterial growth, especially bacteria like Clostridium perfringens and Bacillus cereus, which thrive at temperatures between 40°F and 140°F (the temperature danger zone). Although the lasagna was thoroughly reheated, bacteria such as Clostridium botulinum or toxin-producing bacteria could have produced heat-resistant toxins or spores that survived reheating. These toxins can cause food poisoning even after reheating if the food was contaminated before reheating or not cooled properly initially. Based on the incubation period and symptoms, Clostridium perfringens is a likely cause, as it is commonly associated with improperly cooled cooked foods and causes symptoms such as diarrhea and abdominal cramps within 8-16 hours.
Scenario 3write at least 50-word responses to each of the following questions
Sally and her family’s illness could be caused by consuming contaminated food, possibly from undercooked meats, spoiled dairy products, or contaminated produce. It might also result from cross-contamination or poor kitchen hygiene. To prevent such illnesses, they should ensure proper cooking, storage at appropriate temperatures, and rigorous handwashing and cleaning of surfaces and utensils.
The illness could have been prevented by identifying the contaminated food source, practicing proper food handling, ensuring foods are cooked thoroughly, and maintaining good personal hygiene. Using separate cutting boards for raw meats and vegetables, cooking foods to safe internal temperatures, and refrigerating perishable items promptly are essential steps. Regular cleaning of kitchen surfaces and utensils also helps prevent cross-contamination, reducing the risk of food-borne illnesses among family members.
