It's Peter McGuire Day -- a great time to barbecue. "Who's this McGuire fellow?" you ask. He's the guy who started all this for you -- in 1882. A cabinetmaker in New York City, McGuire proposed a parade to celebrate workers. That September, 10,000 showed up. The idea caught on, and 12 years later President Grover Cleveland made it a national holiday. Today, for many, one man's dream means a day off -- and maybe a barbecue. But, please, barbecue intelligently and safely. When you refill your gas grill's propane tank, be sure you have the new OPD valve that prevents overfilling -- it's now the law. Americans will cook 52 million pounds of beef, 40 million pounds of chicken and 200 million hot dogs. So be sure to remember food safety, as well. Prevent food contamination by washing hands and food-preparation surfaces frequently. Never put cooked food where raw meat was placed earlier. Cook food to proper internal temperatures, and refrigerate all leftovers within two hours. Celebrate your Peter McGuire Day the smart and safe way. And that's the On The House Tip for today.
