However, <strong>its use also presents significant challenges<\/strong>, especially regarding EtO residues in sterilized products and its environmental impact. <\/p>\n<p>Over the years, EtO residue regulations have evolved significantly, establishing stricter regulations to protect patient health and reduce emissions into the environment.<\/p>\n<h3>Major regulatory changes in EtO residue control<\/h3>\n<h4>1. Exposure limits on medical devices<\/h4>\n<p>One of the first advances in the regulation of ethylene oxide waste was the introduction of maximum concentration limits allowed in medical devices, depending on their toxicity and absorption in different materials.<\/p>\n<p><a href=\"https:\/\/www.iso.org\/es\/contents\/data\/standard\/08\/48\/84824.html\" target=\"_blank\" rel=\"noopener\">ISO 10993-7<\/a>, originally published in 1995, established criteria for assessing the presence of EtO residues and its main by-product, 2-chloroethanol (ECH). Over the years, this standard has been revised to improve the accuracy of extraction and quantification methods. <\/p>\n<h4>2. Regulations on atmospheric emissions<\/h4>\n<p>Ethylene oxide residue control not only focuses on medical devices, but also on reducing emissions into the atmosphere.<\/p>\n<ul>\n<li>In the <strong>United States<\/strong>, the Environmental Protection Agency (EPA) has tightened EtO emission limits at sterilization plants, requiring the use of advanced systems such as catalytic oxidation and activated carbon filtration.<\/li>\n<li>In <strong>Europe<\/strong>, the Industrial Emissions Directive (IED) imposes specific restrictions to minimise the release of EtO and promote more efficient and safer processes.<\/li>\n<\/ul>\n<h4>3. Validation and monitoring of EtO residues<\/h4>\n<p>Regulatory bodies have tightened validation requirements for EtO sterilization processes, requiring more data on effective residue removal before medical devices are marketed.<\/p>\n<ul>\n<li>The FDA has increased oversight over validation processes, requiring companies to submit detailed data on the aeration phase and removal of EtO residues.<\/li>\n<li>Regulatory audits now require continuous monitoring of waste disposal, ensuring devices comply with permitted limits.<\/li>\n<\/ul>\n<h4>Solutions for regulatory compliance<\/h4>\n<p>In light of the constant evolution of regulations, at MCI we offer specialized solutions for the evaluation and control of EtO residues in medical devices:<\/p>\n<ul>\n<li>Accredited tests for the detection and quantification of EtO and ECH according to ISO 10993-7.<\/li>\n<li>Validated methods for waste extraction and evaluation, guaranteeing reliable results.<\/li>\n<li>Strategic location in Costa Rica, reducing response times and logistics costs.<\/li>\n<li>Specialized technical advice to interpret results and comply with regulatory standards.<\/li>\n<\/ul>\n<h3>Comply with regulations and ensure the safety of your products<\/h3>\n<p>As EtO residue regulations continue to evolve, MCI remains at the forefront, offering<strong><a href=\"https:\/\/mci-cr.com\/en\/ethylene-oxide-residue-analysis\/\" target=\"_blank\" rel=\"noopener\"> advanced ethylene oxide residue analysis<\/a><\/strong> services to ensure regulatory compliance and safety in the medical device industry.<\/p>\n<p>Contact us for more information about <a href=\"https:\/\/mci-cr.com\/en\/ethylene-oxide-residue-analysis\/#info\" target=\"_blank\" rel=\"noopener\">our testing and validation services<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evolution of regulations on EtO residues in medical devices and [&hellip;]<\/p>\n","protected":false},"author":12,"featured_media":13445,"comment_status":"open","ping_status":"open","sticky":false,"template":"plantilla-noticias.php","format":"standard","meta":{"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","_joinchat":[],"footnotes":""},"categories":[10133],"tags":[],"class_list":["post-13448","post","type-post","status-publish","format-standard","has-post-thumbnail","category-medical-devices","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>EtO Residues in the Medical Device Industry | MCI<\/title>\n<meta name=\"description\" content=\"Evolution of regulations on EtO residues in medical devices and how to comply with new standards.
