Abstract
Bacteriophage-based products are gaining attention as effective tools to reduce harmful germs in food and combat antimicrobial resistance throughout the food production process. However, in South America, their use is still limited because of complicated regulations and inconsistent evidence requirements. This review aims to (i) explore the current scientific and technological landscape of using bacteriophages in South American food systems, (ii) identify main regulatory challenges that impact their classification, approval, and use, and (iii) highlight the need for consistent international guidelines, especially from Codex Alimentarius, to help safely and effectively incorporate phage-based products in food. Research on phage-based products is growing, but it is not consistent across different regions. There are more patents and advancements in biotechnology, but they are limited to certain areas. Although progress is being made, the regulatory frameworks are still unclear, especially when it comes to how these products are classified, labeled, and monitored for safety. To address these gaps, risk-based guidelines are needed. These should define product categories and claims, set safety standards, and include rules for tracking products and monitoring them after they hit the market. Creating a new Codex Alimentarius project on phage-based products could help establish global guidelines that promote safe use, reduce uncertainty in regulations, and improve trade in food markets around the world.
