Premi Test(プレミテスト) 4×25

製品説明

Treatment of farm animals with veterinary pharmaceuticals such as antibiotics leads to drug residues in the tissues of the animals and establishes a health risk for the consumers of animal food products. Premi®Test is an easy antibiotics residue screening test which allows fast screening of food products by all members of the food production chain such as farmers, slaughterhouses, meat-processors and analytical laboratories.

Premi®Test is based on the inhibition of the growth of Geobacillus stearothermopilus, a thermophilic bacterium which is very sensitive to many antibiotics and sulfur compounds. A standardised number of spores are imbedded in agar medium containing selected nutrients. When Premi®Test is heated at 64 °C, the spores will germinate. If no inhibitory substances are present the germinated spores will multiply with the production of acid. This will be visible by a color change from purple to yellow. When anti-microbial compounds are present in sufficient amount (above the detection limit) the spores will be unable to germinate and therefore no color change will be observed.
