Determination of Trichina
Trichina (Trichinella spp.) are small roundworms approximately 1 mm long that live as parasites in the skeletal muscles of mammals, birds and reptiles. They can be transferred to a new host (human or animal) through the consumption of raw meat containing infectious larvae in the muscle tissue. Meat intended for human consumption must be inspected in accordance with Regulation (EU) No. 2075/2005. Carl ROTH offers reagents suitable for this purpose.
Carl ROTH provides suitable acids and bases for different requirements!
Carl ROTH offers an extensive range of calibration and control standards. These products are manufactured from highly pure starting material and are specially tested for each application. The corresponding batch-specific certificate of analysis is available online. Each product series offers excellent value for money.
