London: Being bitten by one of the spider-like bugs can trigger a severe allergy to meat, a new study has revealed.Three cases of the strange reaction were recognized in the US. The patients suffered severe symptoms several hours after consuming red meat.Researchers traced the delayed allergic response to bites from a tick - specifically the Lone Star tick.A carbohydrate compound injected into the bloodstream by the bite is also present in meat. The initial bite is believed to programme the immune system to react next time it encounters the substance.Dr Susan Wolver, from Virginia Commonwealth University, and colleagues said that the result when the unsuspecting victim tries eating a steak can be an outbreak of hives, or even life-threatening anaphylactic shock.
