Departments: Food Safety Goes Global

Risks arising from an improperly designed, implemented, and maintained food safety system can have financially crippling effects, from brand damage, decreased consumer confidence, product recalls, illness, death, and legal ramifications. And, with globalization and an increase in supplies from emerging countries, the likelihood of these risks grows and the processes to manage them effectively become more complex. An additional element in this struggle is the varying acceptance of food safety standards and...

Departments: The Evolution of HACCP

As it approaches its 50th anniversary, hazard analysis and critical control point (HACCP) has repeatedly shown itself to be the most effective system to ensure food safety. The principles can be applied in a variety of venues, from agricultural production to food service, from multinational corporations to small processors in developing countries. It is a systematic approach to building safety.

Departments: A Cool Way to Clean

Keeping food processing surfaces clean is a production manager’s main concern. Removing leftover food, grease, grime, and other residue from production equipment is critical for preventing bacteria growth and ensuring safe, high quality food products. As sanitation regulations become more stringent, labor costs increase, and the industry becomes more environmentally conscious, food companies are looking for new cleaning processes and solutions.

Departments: Protect Your Customers From Gluten

A Google search of the word combination “gluten free” returns a staggering 7 million results. Many provide information regarding gluten-free ingredients, recipes, and prepared foods currently available in the marketplace. This tidal wave of information is the result of the heightened interest in gluten-free diets of an increasing number of people who have been diagnosed with celiac disease (CD).

Departments: Prevent and Control Listeria

Recognized as an important public health problem in the United States, Listeria monocytogenes is a ubiquitous, intracellular pathogen known to cause food-contaminating outbreaks. These microorganisms have the ability to multiply within host cells and spread from cell to cell.

Departments: HACCP Programs and Practices Evolve

This article is based on three webinars from The Microbiology Webinar Series, co-sponsored by AES-Chemunex, Inc. and Carpe Diem, A Wiley Company. Donald Schaffner, PhD, professor and extension specialist at Rutgers University’s School of Biological and Environmental Sciences, was the keynote speaker for both “Challenges in Implementing HACCP: Validation and Verification, Quantitative Risk Assessment: Is it the Next Step After HACCP?” and “Use of Predictive Microbiology to Support...

Departments: The Case for Ozone

In 2000, the Electric Power Research Institute published “Food Industry 2000: Food Processing Opportunities, Challenges, New Technology Applications.” The report contains the following statement: “Ozone destroys bacteria, mold, mildew, spores, yeast and fungus. It inactivates viruses and cysts. Chlorine is not very effective against viruses and has limited effect on some types of bacteria … ozone reacts much faster than chlorine.”

Departments: Protect Your Product From Contaminants

Today’s processing lines are complex and, increasingly, automated, making the detection of foreign contaminants in both raw materials and finished products more challenging than ever. Companies need comprehensive programs to ensure that contaminants never reach the consumer. Good manufacturing processes are an essential component of any overall program.

Departments: Go With the Flow

In the food and beverage and pharmaceutical and biotech industries, contamination-free processing is essential for full compliance with industry validation standards. The potential for contamination in manufacturing applications increases with the introduction of peripheral components, such as flow measurement instruments, that help maintain process parameters within acceptable limits. To prevent this from happening, these devices must themselves meet standards set by governing agencies to ensure that...

Departments: LC/MS/MS Can Help Screen Cereal

Water-soluble vitamins, which are very polar, have poor retention on reverse phase columns. The presence of ion pair reagents such as heptafluorobutyric acid in the mobile phase has been shown to improve the separation and retention of these compounds. The drawback of using such ion pair reagents, however, is the high background levels generated inside the mass spectrometer (MS). Therefore, we have developed a rapid and sensitive method with ammonium formate in the mobile phase solvent using a column with...
