Traces Of Human, Rat DNA Found In Some Hamburger Meat Samples

MENLO PARK (CBS SF) — An analysis of hamburger meat sold in stores and restaurants in Northern California found some samples with traces of human and rat DNA, along with some substituted ingredients or others not found on the label.

Menlo Park-based Clear Labs took a look at more than 250 hamburger products, including ground meat, frozen patties, fast food burgers and veggie burgers. The ground meat included beef, chicken, turkey, pork and others.

The analysis found contamination, hygenic or substitution problems in 13.8 percent of the products sampled from dozens of brands and retailers. Examples would be meats observed in molecular analysis but not shown on the label, absence of ingredients advertised on the label, or trace amounts of DNA from humans, insects or rats.
