Even small amounts can cause nausea and vomiting; in rare cases, severe, life-threatening symptoms have also been reported. Since the toxin is not inactivated by heating, preventive analysis along the food chain plays a crucial role.<\/span><\/span><\/span><\/span><\/p>\n<p><span style=\"font-family: Tahoma, sans-serif;\"><span style=\"font-size: medium;\"><b>Challenges in detecting emetic B. cereus<br \/>\n<\/b>An important aspect in the evaluation of <i>Bacillus cereus<\/i> in food is the distinction between apathogenic strains and those with emetic potential. Classic cultural detection methods or non-specific <i>B. cereus<\/i> tests provide only limited information for this purpose, as they do not allow any conclusions to be drawn about the ability to form cereulide.<br \/>\nThe BfR also points out that cereulide does not necessarily have to be formed in the end product, but can already enter food via contaminated ingredients. This makes it all the more important to identify toxin-producing strains early and specifically.<\/span><\/span><\/p>\n<p><span style=\"font-family: Tahoma, sans-serif;\"><span style=\"font-size: medium;\"><b>Contribution to food safety and prevention<\/b><br \/>\nAgainst the backdrop of current events, molecular biological detection methods such as real-time PCR underscore their high value in food safety.
