There’s nothing nicer than getting together with friends and family to cook your favorite foods over a grill. This is a primal ritual than goes back thousands of years across all cultures. But most people don’t know that grilling meat means exposure to carcinogenic chemicals.
Whenever you grill meat over a hot flame you will create hazardous compounds called heterocyclic amines (HCAs). Some of those nasty chemicals may be left over on the grill and that is why proper cleaning is critical. But how you clean your grill and then how you cook your meat can make a tremendous difference. That’s why we have gathered some simple solutions to make barbecuing safer this summer.
CLEANING THE GRILL
Most grillmeisters want to make this part of the process quick and easy so they can get down to the serious business of barbecuing. The usual approach is to run a metal brush over the grill a few times to remove most of the left overs from the last barbecue. Rarely does anyone look closely to see whether a) the gunk has actually been removed effectively and b) are there any metal wires left on the grill that could end up in the food and eventually swallowed. The CDC reported a couple of years ago about “Injuries from Ingestion of Wire Bristles from Grill-Cleaning Brushes”:
“Foreign object ingestion is a common reason for visiting an emergency department (ED), particularly for children. In recent years, internal injuries have been reported following unintentional ingestions of wire grill-cleaning brush bristles by both children and adults…This report describes a series of six more cases identified at the same hospital system during March 2011-June 2012. The six patients ranged in age from 31 to 64 years; five were men. Like the patients in the previous series, all six reported outdoor residential food grilling and use of commercially available wire grill-cleaning brushes. The severity of injury ranged from puncture of the soft tissues of the neck, causing severe pain on swallowing, to perforation of the gastrointestinal tract requiring emergent surgery…Before cooking, persons should examine the grill surface carefully for the presence of bristles that might have dislodged from the grill brush and could embed in cooked food. Alternative residential grill-cleaning methods or products might be considered.”
So, how can you clean a grill effectively without leaving behind tiny metal wires that could puncture the neck or perforate the GI tract? One suggestion is to “Go Wireless.” You can swipe a cut onion over the hot grate. It is supposed to clean off the grease and grime.
You could also use a nylon bristle brush to clean a cool grill without leaving metal wires behind.
If you are going to a camp ground with those heavy-duty built-in grills that have round grates, consider “Grillfloss.” This device allows you to clean both the top and bottom of the metal rods.
Of course there is always good old-fashioned hand scrubbing. It will require removing the grates from your grill. Buy a dish-washing scrubber and use a little detergent to get the grime, grease and gunk off your grill. Then rinse the grate thoroughly and throw out the scrubber.
Once your grill is clean, you are almost ready to barbecue. But wait, you need to prepare your meat beforehand if you want to reduce exposure to HCA carcinogens. There is a magnificent article published in the journal Mutagenesis (Nov. 2004). You can read the full text of this article at this link. In a nutshell, here are the recommendations from these scientists:
- Select lean cuts of meat or trim away as much fat as possible
- Marinate your meat or fish before cooking. The best marinades contain some of the following ingredients: onions, garlic, rosemary, extra virgin olive oil, vinegar, lemon juice or yogurt.
- Microwave briefly before grilling. Discard the juice that collects in the bottom of the container. Those juices cause mischief. Getting rid of them dramatically reduces the formation of HCA mutagens.
- Use low heat. The higher the heat and the more flames, the greater the likelihood of carcinogens forming. Flip often. That way you reduce the intensity of the heat on the surface of the meat, chicken or fish.
Last step, enjoy the camaraderie of family and friends. After all, that is the best part of the experience.
