Are Grilled Meats Carcinogenic? BU Health Researcher’s Tips for Safer BBQ
By Food Scan Genius Staff
Last summer, Boston parent Lisa M. watched her son break out in hives after a backyard BBQ. She wondered: was it the marinade, the meat, or something else? Like many families, Lisa loves grilling, but worries about hidden dangers—especially after reading headlines about grilled meats and cancer risk. If you’ve faced similar dilemmas, you’re not alone. Recent research from Boston University and food safety authorities offers practical, science-backed tips to enjoy grilling more safely.
Why Are Grilled Meats Linked to Cancer?
When meats are cooked at high temperatures—especially over open flames—two types of potentially carcinogenic compounds can form:
- Heterocyclic amines (HCAs): Created when amino acids and creatine in muscle meats react at high heat.
- Polycyclic aromatic hydrocarbons (PAHs): Produced when fat and juices drip onto flames, creating smoke that coats the meat.
Both HCAs and PAHs have been found to cause DNA changes in laboratory studies, increasing cancer risk (National Cancer Institute, PubMed).
BU Health Researcher’s Science-Backed Grilling Tips
In a recent Boston University article, Dr. Jennifer Yee, a registered dietitian and BU researcher, shared actionable ways to reduce carcinogen formation:
| Tip | How It Helps |
|---|---|
| Marinate Meats | Using marinades with vinegar, lemon, or herbs can cut HCA formation by up to 90% (PubMed). |
| Pre-Cook in Microwave or Oven | Reduces grill time, limiting exposure to high heat and smoke. |
| Grill Lean Cuts | Less fat means fewer drips and less PAH-laden smoke. |
| Flip Often | Frequent turning prevents charring and burning. |
| Avoid Direct Flame | Cook over indirect heat or use foil to minimize charring. |
| Trim Charred Bits | Remove blackened parts before eating. |
Q: Is grilling plant-based meats safer?
A: Plant-based proteins generally form fewer HCAs and PAHs when grilled, making them a safer alternative (EFSA).
Stay Informed: Food Safety News & Dietary Trends
- Product Recalls: The FDA recently recalled several beef products due to E. coli contamination. Always check for alerts before grilling.
- Labeling Laws: The U.S. FDA requires clear allergen labeling, while the EU’s EFSA enforces even stricter ingredient disclosures. For example, sesame became the 9th major U.S. allergen in 2023 (FDA).
- Emerging Trends: Plant-based grilling is on the rise, with brands like Beyond Meat reformulating for cleaner labels (Food Dive).
These developments matter for people with food sensitivities, allergies, or dietary preferences. Ingredient transparency and up-to-date safety info can help you avoid hidden risks and make ethical choices.

US vs. EU: Labeling Laws & Allergen Disclosure
| Regulation | United States (FDA) | European Union (EFSA) |
|---|---|---|
| Allergen Disclosure | 9 major allergens must be listed; sesame added in 2023 | 14 allergens required, including celery, mustard, lupin |
| Ingredient Labeling | Ingredients listed by weight, descending order | Similar, but stricter on additives and processing aids |
| Carcinogen Warnings | No specific warning for HCAs/PAHs | EFSA monitors PAH levels in foods, issues advisories |
FAQs: Grilled Meats, Carcinogens, and Food Safety
Are all grilled meats carcinogenic?
Not all grilled meats are equally risky. The formation of HCAs and PAHs depends on cooking method, temperature, and meat type. Using marinades, lower heat, and lean cuts can significantly reduce risk.
What are the safest ways to grill meat?
Marinate meats, grill over indirect heat, trim fat, flip often, and avoid charring. Consider pre-cooking in the microwave or oven to reduce grill time.
How can I stay updated on food recalls and safety alerts?
Use the Food Scan Genius app for instant alerts, or check FDA and EFSA websites regularly for updates.
Is grilling plant-based meat safer?
Yes, plant-based proteins generally produce fewer carcinogens when grilled compared to animal meats.
Conclusion: Grill Smarter, Eat Safer
