However, unlike many other foodborne toxins, it has historically not been subject to harmonized regulatory limits at the international level. As a result, food safety controls have primarily focused on the detection and enumeration of&nbsp;<em>Bacillus cereus<\/em>, rather than on the&nbsp;<strong>direct measurement of the toxin<\/strong>&nbsp;itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The absence of defined toxicological reference values has made the interpretation of findings complex for food business operators. Crucially, cereulide production is&nbsp;<strong>not directly correlated with bacterial counts<\/strong>; compliance with microbiological criteria does not necessarily guarantee the absence of toxin-related risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Recent detections of\u00a0<strong>cereulide in\u00a0<\/strong><a href=\"https:\/\/mxnsaq.com\/sg\/baby-food\/\" data-type=\"page\" data-id=\"4516\"><strong>baby formula<\/strong><\/a><strong>\u00a0(infant formula)<\/strong>\u00a0have drawn increased attention to this regulatory gap.

They remain resistant to common food processing methods such as boiling and pasteurization. Consequently, conventional microbiological tests focusing solely on bacterial presence are insufficient: even when spores are inactivated, the toxin may persist in the food matrix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The toxin\u2019s stability and its tendency to interact with specific food components complicate sampling. In some investigations, contaminated ingredients tested negative for the toxin until they were incorporated into finished products, illustrating how food matrices influence detectability. Because of these properties,&nbsp;<strong>analytical approaches must be specifically designed to identify and quantify the toxin itself<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How M\u00e9rieux NutriSciences Addresses Cereulide Testing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As regulatory authorities move toward health-based guidance values\u2014with an acute reference dose (ARfD) of 0.014 \u00b5g\/kg body weight for infants\u2014highly sensitive analytical methods are required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To address these challenges and meet the new thresholds defined by EFSA, M\u00e9rieux NutriSciences has developed\u00a0<strong>specific analytical solutions focused on the direct detection and quantification of cereulide in food<\/strong>\u2014specifically baby food (infant formula and follow-on formula), milk powder, ARA oil, ARA powder,\u00a0<a href=\"https:\/\/mxnsaq.com\/sg\/cereals-flours-bakery\/\" data-type=\"page\" data-id=\"4785\">cereals<\/a>.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">LC-MS\/MS (Liquid Chromatography-tandem Mass Spectrometry)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">M\u00e9rieux NutriSciences has implemented dedicated methodologies based on&nbsp;<strong><a href=\"https:\/\/www.iso.org\/standard\/62512.html\" target=\"_blank\" rel=\"noreferrer noopener\">ISO 18465<\/a><\/strong>, using&nbsp;<strong>LC-MS\/MS (liquid chromatography-tandem mass spectrometry)<\/strong>, providing the sensitivity and robustness needed to reach new EFSA recommendations.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">QuEChERS Sample Preparation Protocol<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As cereulide is a lipophilic cyclic peptide, it is essential to use specific sample preparation protocols.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Analytical methods based on the well-established QuEChERS sample preparation protocol have been developed for selected matrices and raw ingredients, enhancing sensitivity and overall method robustness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach is allowing us to reach lower LOQs compared to the ISO method.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Network of Laboratories to Ensure Results Comparability<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Our network of laboratories can support you with aligned methodologies, ensuring analytical reliability and\u00a0<a href=\"https:\/\/www.merieuxnutrisciences.com\/food\/laboratory-testing\/merieux-nutrisciences-one-quality-system\/\" target=\"_blank\" rel=\"noopener\">result comparability across our global network of laboratories<\/a>.
