Consumer and regulatory demand for naturally derived alternatives to synthetic food colorants is on the rise. To meet that demand, Cornell University scientists have developed a new blue food dye made of algae protein.

Researchers in China have developed a new onsite rapid test, based in fluorescence RNA-targeted isothermal amplification assay (SAT) technology, that can quickly detect and identify Cronobacter species in powdered infant formula. It offers significantly greater sensitivity and much more rapid results than polymerase chain reaction (PCR), without producing false positives.

Ionophores—a class of antibiotics that are used widely in animal production but are not used in human medicine—may contribute to the development of medically important antimicrobial resistance (AMR), a new study suggests.

A recent analysis of French milk and infant formulas has revealed the presence of titanium dioxide—which is banned as a food additive in the EU due to potential toxicity—in all human and animal milk samples, as well as in most infant formula samples. Researchers raise concerns about implications for infant health, and question routes of exposure leading to contamination.

This episode of Food Safety Five discusses a new study that leverages a novel quantitative microbial risk assessment (QMRA) model that suggests that half of E. coli O157:H7 illnesses linked to romaine lettuce are caused by contamination via untreated overhead irrigation water.

A laboratory study and large-scale commercial wheat mill trial demonstrated that a bacteriophage cocktail can significantly reduce Shiga toxin-producing Escherichia coli (STEC) O157:H7 contamination throughout milling operations without affecting the baking qualities of flour.

On July 29, the Senate confirmed Trump Nominee Susan Monarez, Ph.D. as the new director of the U.S. Centers for Disease Control and Prevention (CDC). She is an immunologist and microbiologist, and the agency’s first non-physician Director in more than 70 years.

According to the 2025 International Food Information Council (IFIC) Food and Health Survey, consumer confidence in U.S. food safety has hit an all-time low in the 13 years since the survey began gauging the metric. Foodborne bacteria are the number one ranked concern in 2025, and attention to food additives and ingredients is rising. 

The Reagan-Udall Foundation for FDA has published a report based on months of stakeholder dialogues, titled, the Roadmap to Produce Safety, which provides recommendations for a private sector-led collaborative to improve U.S. produce safety.

A peer-reviewed study led by CU Boulder researchers demonstrates that erythritol, a popular non-nutritive sugar alcohol that is commonly used as a zero-calorie sweetener in “sugar-free” snacks and beverages, may increase stroke risk by may constricting the brain’s blood vessels and lowering the body’s ability to dissolve blood clots.
