In the latest issue of the Journal of Food Protection, published by the International Association of Food Protection, significant concerns regarding the food safety risks posed by disposable gloves have been brought to light.
The journal underscores scientific findings revealing the presence of hazardous chemicals and pathogens on disposable gloves, potentially leading to food contamination. Even when meeting FDA compliance standards, new and unused disposable gloves are shown to be potential sources of contamination.
Despite their widespread use as essential food safety equipment, glove contamination remains a substantial oversight in public health, warranting urgent attention.
The article in the Journal sheds light on the loosely regulated manufacturing of gloves, citing inadequate quality controls and verification processes. This lax oversight can lead to the production of low-cost gloves under unsanitary conditions and the utilization of cheap and unsafe chemicals.
Collaborating with Eagle Protect, consultant microbiologists from the B. Michaels Group stress the necessity for more rigorous testing and validation of gloves to ensure they meet stringent safety standards before use. The article emphasizes the integration of robust glove safety measures into Hazard Analysis Critical Control Points (HACCP) and Food Safety Modernization Act (FSMA) programs to prevent contamination incidents.
Analysis conducted by the B. Michaels Group revealed the presence of human fecal indicator organisms, Bacillus cereus and B. anthracis strains, and other pathogens on new and unused disposable gloves. Hazardous chemicals such as per and polyfluoroalkyl substances (PFAS), phthalates, and bisphenol A (BPA) were also detected. Testing encompassed 2,800 gloves from 26 different brands.
Key excerpts from the Journal article underscore the potential risks posed by gloves:
- “Gloves have been identified as sources of potentially toxic, poisonous, and deleterious chemicals that can be introduced into food and cause dermal problems via solubilization of glove chemicals within gloves via sweat.”
- “With their treatment as simple consumable commodities by food industry procurement staff, there is a lack of validation or verification of safe and acceptable performance that should be pre-requisite program elements in adherence to HACCP and FSMA principles.”
The review primarily focuses on the direct physical, chemical, and microbiological contamination risks associated with disposable gloves in food environments, highlighting threats to both food products and worker safety. Weaknesses in glove manufacturing processes, exacerbated by the COVID-19 pandemic’s demands, are underscored, including high demand, supply chain instability, and labor shortages.
Citing multiple evidence-based reports, the article indicates systemic shortcomings within the glove industry, including contamination, toxicity, illnesses, deaths, and associated regulatory actions. The manufacturing process of gloves is diagrammed, pinpointing sources and pathways of contamination and revealing documented occurrences of weak points.
Numerous unsafe ingredients in gloves can introduce chemical contaminants, posing risks to both food and glove users. Microbial hazards present further challenges to glove safety, with contaminants introduced via polluted water sources or flawed manufacturing processes. Both frank and opportunistic pathogens, as well as food spoilage organisms, can be transmitted to foods and wearers.
Exploration of the sources and pathways of glove-borne contamination reveals that physical failures, including punctures in new gloves, play a pivotal role in the release of sweat buildup, liquefaction of chemical residues, and incubation of microbial contaminants. Thus, physical, chemical, and microbiological contamination can occur, potentially leading to foodborne illnesses.
The article concludes by advocating for enhanced regulatory requirements for Acceptable Quality Limits of food-grade gloves and establishing appropriate bioburden standards to improve safety in food applications. It suggests that the unconditional belief in glove purity may be unfounded, emphasizing the need for a critical reevaluation of glove safety standards and practices.
