Food Safety Scavenger Hunt
Ever wonder how the foods in your home are kept safe? The scavenger hunt activity challenges you to find different types of foods based on how they're processed and preserved.
You might find fruits without blemishes (like oranges), foods that haven't been treated at all (like fresh salad), or items processed through different methods like fermentation (wine) or ultra-high temperature treatment. You'll also look for washed produce, thermally processed foods (canned goods), irradiated foods, and pasteurized products like milk.
This activity helps you recognize how common food safety practices are already part of your daily life. Most foods we eat have gone through some form of processing to keep them safe and extend their shelf life.
Did you know? Food processing isn't new! Humans have been preserving foods through drying, smoking, and fermenting for thousands of years before refrigeration was invented.
Understanding HACCP Food Safety Systems
HACCP (Hazard Analysis Critical Control Point) is like a roadmap for making food safely. In this activity, you'll observe someone preparing food and create a process flow diagram showing every step from start to finish.
The example shows a homemade barbecue preparation process: washing meat, adding ingredients (soy sauce, garlic, pepper, etc.), slicing, packaging, marinating with bare hands, adding calamansi juice, freezing, and finally grilling. Each step is mapped out to show the complete journey from raw ingredients to finished meal.
After creating your flow chart, you'll analyze each step for potential safety hazards. This helps identify the most critical points where contamination or other food safety problems could occur.
Safety Tip: Identifying critical control points in food preparation isn't just for professional chefs—it's a skill that can help keep you and your family safe from foodborne illness!
Identifying Critical Control Points
When analyzing food preparation for safety, you need to determine which steps are truly critical. For the barbecue example, washing meat is identified as a critical control point because water quality and flow can affect food safety.
For each critical step, you'll need to:
- Identify potential hazards (like contamination from tap water)
- Decide if the hazard needs to be addressed
- Justify your decision with evidence
- List control measures to reduce the risk
- Establish critical limits
Another critical point identified is packaging. The container used might not be properly disinfected, which could lead to contamination. The control measure is ensuring proper sanitation using disinfectants that kill 99.9% of germs or using hot water (approximately 100°C).
Remember: In food safety, prevention is always better than dealing with contamination after it occurs. Taking proper precautions at critical points makes a huge difference!
Hand Hygiene and Temperature Control
Marinating meat by hand presents another critical control point in food preparation. When food handlers touch ingredients directly, there's a high risk of contamination that could cause serious illness if not prevented.
The control measure for this step is proper hand hygiene—washing and sanitizing hands before food handling to ensure they're 99.9% free of germs. This simple step dramatically reduces the risk of foodborne illness.
Storage temperature is equally crucial for food safety. Incorrect storage temperature can lead to rapid microbial growth and food spoilage. For marinated meat, the temperature should be kept at 40°F to prevent dangerous bacteria from multiplying.
Pro Tip: Set your refrigerator to 40°F (4°C) or below and check it occasionally with a refrigerator thermometer. Bacteria grow most rapidly between 40°F and 140°F—a range food safety experts call the "Danger Zone."
Safe Grilling Practices
The final critical control point in our barbecue example is grilling. When meat is grilled, there's a risk of harmful compounds forming if the food becomes charred or burnt.
Both charcoal and wood fires can emit pollutants like soot and hydrocarbons that are harmful to health. These compounds can form when meat is cooked at too high a temperature or for too long.
To control this hazard, you should monitor the grill temperature and cooking time carefully. The critical limit is to keep the grill temperature below 265°F (130°C) to avoid charring. This prevents the formation of potentially harmful compounds while still ensuring the meat is thoroughly cooked.
Grilling Safety: Besides temperature control, always clean your grill before cooking, use separate utensils for raw and cooked foods, and check meat with a thermometer to ensure it reaches a safe internal temperature.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades
