(FOX News) - If you're already suspicious about what's in a hot dog, drilling down to the molecular level may be even more shocking.
According to food researchers at startup lab Clear Food, who tested 345 hot dog samples from 75 different food brands, 14.4 percent of hot dogs "were problematic in some way."
Those problems include finding meat in hot dogs labeled as vegetarian and pork in dogs label as kosher.
The report found human DNA in 2 percent of samples, two-thirds of which were vegetarian-labelled hot dogs.
To get the results, Clear Food used new technology to examine food at the molecular level which catches allergens and hidden additives other food tests can miss.
