Man suffers deadly allergic reaction that's been traced back to ticks

A college professor suffered a near-fatal allergic reaction to barbecue meat in what is believed to be one of the first cases of its kind.

State professor Brian McCornack went into anaphylactic shock and was rushed to the ER hours after eating steak that was cooked on an outdoor grill.

The devastating complication occurs when the body releases a flood of chemicals in response to an allergen, in this case a compound in red meat.
