In response, Indian drug regulatory authorities and the Indian Pharmacopoeia have implemented several measures to enhance the quality, safety, and efficacy of pharmaceuticals manufactured in India. These measures encompass risk-based inspections of manufacturing facilities, rigorous quality control checks of medicinal products intended for export, and increased transparency in the supply chain of excipients prone to EG and DEG contamination. Further, the Indian Pharmacopoeia has updated monographs for five high-risk excipients: glycerin, propylene glycol, sorbitol solution (70%, both crystallizing and non-crystallizing), and liquid maltitol.

The present review evaluates how various categories of food-relevant substances are considered in terms of being 'contaminants'. To this end these categories of food borne constituents are evaluated against the various criteria encountered in the available definitions of a food contaminant, including unintentional presence, harmful, existence of regulatory limits, and stakeholder perception. The categories of chemicals considered include: phytotoxins, mycotoxins, (heavy) metals, persistent organic pollutants (POPs), processing aids, process related contaminants, food contact materials (FCMs), pesticides and veterinary drugs. The evaluation revealed that usage of the term appears complex, and may differ between stakeholders. A common proposed definition of the term 'contaminant' could be 'a substance considered to require control measures due to the unacceptability of its context within a food'. Use of a dimension of harm results in equivocal outcomes because risk depends on the level of exposure. As the term 'contaminant' has influence on risk management including public policy, the motivations for applying the term should be subject to more detailed analysis and understanding.</p>","PeriodicalId":20852,"journal":{"name":"Regulatory Toxicology and Pharmacology","volume":" ","pages":"105739"},"PeriodicalIF":3.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142639666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some companies considered using minipigs more often due to NHP shortages and regional ethical concerns with using NHPs and dogs. However, for most pharmaceutical companies, minipigs still represent ≤5% of their nonrodent animal use. Key challenges noted by companies to wider adoption of minipigs were high test article requirement, limited historical control data, and lack of relevant reagents or assays. Additionally, some companies expressed uncertainties about contract research organization (CRO) capabilities and experience, a perception not shared by respondent CROs.
