Safety

Dr. Salah Issa’s career in agricultural safety began in an unexpected way. Starting out at a graduate program in Ecological Sciences and Engineering at Purdue University as a self-described “city kid”, he was unaware that agricultural engineering was even a career option. It wasn’t until he took a course in agrosecurity that the world of agriculture, and its hazards, opened up to him. 

Scientists have spent decades genetically modifying the bacterium Escherichia coli and other microbes to convert carbon dioxide into useful biological products. Most methods require additional carbon sources, however, adding to the cost. A new study overcomes this limitation by combining the photosynthetic finesse of a single-celled algae with the production capabilities of the bacteria E. coli.

The researchers report their results in the journal Metabolic Engineering.

You’ve probably heard of product recalls involving lettuce, spinach, or other leafy greens. Consuming these popular vegetables is among the main causes of food poisoning, affecting thousands of people every year. Leafy greens can become contaminated with pathogenic E. coli or other bacteria through splashes of soil or contaminated irrigation water in the field, or through processing and handling. Growers and processors work hard to implement multiple safety procedures, but contaminated products still slip through the cracks and reach consumers.

Fungal contamination of cereal grains poses a substantial threat to food security and public health while causing hundreds of millions of dollars in economic losses annually. In a new study, researchers at the University of Illinois Urbana-Champaign evaluated far-ultraviolet C (far-UVC) light as a safe way to alleviate fungal contamination of corn and wheat and found this technology to be effective.

CSL Behring, a global biomedical company and industry partner of the University of Illinois Urbana-Champaign, recently donated 750 safety goggles to the College of Agricultural, Consumer and Environmental Sciences. The Integrated Bioprocessing Research Laboratory organized the donation, which will be kept on-site for staff and student interns engaged in projects requiring protective eyewear. 

Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year. A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts. The researchers suggest regulation efforts should focus on detecting and preventing those types of high-risk contamination.

At the University of Illinois Urbana-Champaign, safe workplaces have always been a priority. For Daniel Gaither, director of safety for the College of Agricultural, Consumer and Environmental Sciences (ACES) at U. of I., they’re a passion. To observe World Safety and Health Day this year, Gaither reflects on what safety looks like for the vibrant community of students, faculty, and staff in ACES.

Agricultural occupations are  hazardous with one of the highest rates of workplace injuries and fatalities in the U.S. The manual and often strenuous nature of the work, combined with the use of machinery and exposure to environmental hazards create a challenging work environment. Understanding the nature and causes of injuries can help improve safety guidelines and policy measures. However, obtaining a comprehensive overview of injuries is hindered by the absence of a central reporting system.

Leafy green vegetables are important sources of dietary fiber and nutrients, but they can harbor harmful pathogens. In particular, lettuce has often been involved in outbreaks of foodborne illness across the U.S. A new study from the University of Illinois Urbana-Champaign examines factors that affect E. coli contamination on five different leafy greens – romaine lettuce, green-leaf lettuce, spinach, kale, and collards. 

URBANA, Ill.  – Producers of infant formula employ comprehensive food safety systems, including product testing to ensure those systems are working. A new study from the University of Illinois Urbana-Champaign finds that some testing methods are more powerful at catching contaminants than others.
