In the scorching summer, late-night ice cream, afternoon fruit salads, ready-to-eat ham slices... Among these frequent visitors to your refrigerator, a "silent killer" may be lurking—Listeria monocytogenes.
It is resistant to low temperatures, salt, acids, and alkalis, and can quietly multiply even in refrigerators. If ingested, it can cause diarrhea and fever in mild cases, and be life-threatening in severe cases.
Traditional detection methods are time-consuming and difficult to interpret, while chromogenic culture media offer intuitive and efficient advantages. Among these, high-quality chromogenic substrates are key factors determining detection sensitivity and specificity.
We recommend X-Phos-Inositol chromogenic substrate, specifically designed to identify Listeria monocytogenes. Domestically produced with quality comparable to imported products, it releases a blue-green signal for stable coloration, making detection more efficient and reliable.
