Return of the World Milk Day quiz

At long last, we’ve completed another 584 million mile trip around the sun and once again World Milk Day graces our calendars.

Every year, on June 1, the entire globe celebrates the many ways the dairy sector has enriched the world’s food supply — as well as our lives and diets.

Last year, we tried […]

Shining a light on ATP systems

What do fireflies and ATP, or adenosine triphosphate, hygiene monitoring systems have in common?

The science behind the instant detection of organic matter by ATP systems finds its origins in the study of fireflies. In these insects, two chemicals, luciferin and luciferase, react with the molecule ATP, which is found in every living cell, to […]

CDC reminds public not to wash raw chicken; some consumers still doubtful

Health agencies have shared the message again and again: Washing raw meat just causes the bacteria to splash around your sink, your hands and your clothes.

The U.S. Centers for Disease Control and Prevention (CDC) tweeted a reminder about this fact recently: “Don’t wash your raw chicken! Washing can spread germs from the chicken to […]

Evaluating the general public’s food allergen knowledge gap

People who work in food production and processing, as well as food-allergic individuals, can tell you a lot about food allergens — what they are, how they work, and even how they are regulated and labeled. A new study shows, however, that the general public may still have a knowledge gap about food allergens, […]

CDC says foodborne illness rising: What does that really mean?

This week, the U.S. Centers for Disease Control and Prevention (CDC) announced its findings for last year’s foodborne illness rates: reports of Salmonella, Campylobacter and Cyclospora infections were up.

Hold up, though. Are more people getting sick? Not necessarily.

The CDC recently published research suggesting that the increase may be due to better testing […]

Outbreak alert: Listeria monocytogenes in deli meats and cheeses

Four U.S. states have been affected by an outbreak of Listeria monocytogenes, a hardy foodborne pathogen that can survive in a variety of environments, making it challenging for food producers and processors to eradicate in their facilities.

The bacteria has sickened eight people in the ongoing outbreak, resulting in one death. The states impacted are […]

Case study: How a dairy processor improved quality with Neogen’s Soleris system

Neogen’s Soleris system is a rapid optical system for the detection of microbial contamination. It’s based on an innovative application of classic microbiology — the assay measures microbial growth by monitoring pH and other biochemical reactions that generate a color change. The results are monitored by the system, which provides an alert for samples that […]

Adulteration: DNA project reveals fishy nature of fish labeling

In a restaurant, it’s usually obvious when the server brings out the wrong order. Sometimes, however, it may require advanced DNA testing to even realize the order isn’t what you expected.

Dr. Jennifer McDonald, a biology professor at Fanshaw College in Ontario, Canada, directed her molecular biology students on a homework assignment that would […]

Food safety gains increasing clout on social media

The food safety community has spent much of the past few years discussing a perceived increase in foodborne illness outbreaks — and the actual increase in food recalls due to them. We know that the apparent increase is simply attributable to better reporting methods and technologies that make it easier to catch outbreaks and spread […]

Science: Cheese tastes stronger when injected with hip-hop

Expectant mothers often put headphones on their bellies for their babies to listen to as they develop, but it’s a little less common to see cheesemakers doing the same with their wheels of Brie and Camembert.

Nothing wrong with seeing what would happen if they did, said one team of Swiss researchers. The scientists placed […]
