Recent Advances in Sources, Migration, Public Health, and Surveillance of Bisphenol A and Its Structural Analogs in Canned Foods
AI summary Read the abstract
This review examines how bisphenol A and related chemicals migrate from the linings of canned food containers into the food itself, potentially affecting human health. Researchers summarized the latest findings on the sources, migration pathways, and analytical methods used to detect these endocrine-disrupting compounds. The study highlights ongoing concerns about low-level but chronic human exposure to these chemicals through everyday canned food consumption.
The occurrence of bisphenol A (BPA) and its structural analogs, known as endocrine disruptors is widely reported. Consumers could be exposed to these chemicals through canned foods, leading to health risks. Considerable advances have occurred in the pathogenic mechanism, migration law, and analytical methodologies for these compounds in canned foods. However, the confusion and controversies on sources, migration, and health impacts have plagued researchers. This review aimed to provide insights and perspectives on sources, migration, effects on human health, and surveillance of these chemicals in canned food products. Current trends in the determination of BPA and its structural analogs have focused on mass spectroscopy and electrochemical sensor techniques. Several factors, including pH, time, temperature, and volume of the headspace in canned foods, could affect the migration of the chemicals. Moreover, it is necessary to quantify the proportion of them originating from the can material used in canned product manufacturing. In addition, adverse reaction research about exposure to low doses and combined exposure with other food contaminants will be required. We strongly believe that the information presented in this paper will assist in highlighting the research needs on these chemicals in canned foods for future risk evaluations.

Chemical contaminants entering food products from polymer packaging. Review
AI summary Read the abstract
This paper investigates how chemical additives and breakdown products from polymer-based food packaging migrate into the foods they contain. It identifies key contaminants of concern—including plasticizers, stabilizers, and monomers—and evaluates the conditions such as temperature and contact time that accelerate migration, with direct relevance to food safety standards.
Review of Recent Issues in Food Safety of Packaging Materials : Regulatory Concerns and Scientific Findings
AI summary Read the abstract
This review examines recent food safety concerns related to packaging materials, focusing on the migration of chemicals like bisphenol A, phthalates, and PVC from packaging into food, as well as microplastic ingestion risks. Researchers found that while major regulatory bodies have strengthened controls, regional differences in regulations and emerging technologies like biodegradable plastics and nanomaterials introduce new safety questions. The study highlights the need for continued scientific research into how packaging chemicals affect the endocrine system and human health.
Bisphenol A and its analogues: from their occurrence in foodstuffs marketed in Europe to improved monitoring strategies—a review of published literature from 2018 to 2023
AI summary Read the abstract
This review tracks the levels of bisphenol A (BPA) and similar hormone-disrupting chemicals in food and beverages across Europe from 2018 to 2024. While BPA remains the most commonly detected compound, its substitutes (like BPS and BPF) are increasingly found in food packaging and canned goods. These chemicals mimic estrogen in the body and have been linked to reproductive, metabolic, and developmental health concerns.
Simultaneous Determination of Bisphenol A and Its Analogues in Food Matrixes: Cumulative Exposure Assessment Following New Regulatory Restrictions—A Systematic Review
AI summary Read the abstract
As bisphenol A faces near-zero regulatory limits in the EU, food exposure assessments show that combined dietary intake of BPA and its structural analogues can push the cumulative Hazard Index above 1, particularly as less-regulated analogues fill its place. This is critical for microplastic research because plastic food packaging is the primary dietary exposure route for bisphenols, and the substitution problem mirrors broader challenges in regulating plastic-derived chemical pollutants.
