The invention is a rapid and sensitive LAMP assay with specific primers for detecting multiples meat spp. for food authentication or adulteration. It can detect DNA of three meat spp.; rat, cat and dog which are yet to be available in the rountine halal analysis which is normally focusing on porcine elements.The LAMP model provides a sensitive detection of cat, dog and rat meat DNA while being cheaper and faster than the current PCR approaches.This assay is using a portable fluorometer (Genie® II, Optigene, UK), which is a very compact, lightweight and easy to use instrument with built-in rechargeable LithiumPolymer battery; making the whole assay suitable for use not only in the laboratory but also in the field.
