For centuries, silver has offered an alternative use as an antimicrobial—an agent that kills or inhibits the growth of microorganisms. Specifically, Silver Dihydrogen Citrate (SDC) has the capability to usher in a new era of effectiveness in killing germs on hard surfaces and opening a range of opportunities for which silver and SDC-based products can be used.
Could that omnipresent tool of high school chemistry labs—litmus paper, which indicates if a liquid solution is acidic or basic—be harnessed as perhaps the simplest assay yet for foodborne pathogens? Researchers were able to correlate levels of E. coli bacteria with pH values represented by the changing color of the litmus paper.
A scoop of raw dog or cat food may also come with a serving of pathogens, posing potential risk to both pets and their human caretakers. Recent research investigated samples of raw dog and cat foods, exotic animal food, and jerky-type treats for presence of food safety pathogens.
Growing concerns about antibiotic-resistant bacteria are outlined in a recent report by the President’s Council of Advisors on Science and Technology, in a White House National Strategy on Combating Antibiotic Bacteria, and in a Presidential Executive Order. All aim at directing national and international attention toward correction action, including changes in antibiotic use in food production.
Livestock raised on feed that contains genetically modified ingredients—in other words, approximately 95 percent of the food-producing animals in the U.S. today—show no signs of differences in performance or health, according to a new study from researchers at the University of California-Davis. They also found no differences in the nutritional makeup of the food products derived from these animals.
Proposed revisions to four rules in the FDA FSMA are intended to make the original proposals more flexible and practical. The revisions are based on comments received from farmers and others directly affected by the original proposals, and the revisions are now open to public comment.
The FDA is hoping that the prospect of $500,000 in prizes will spur the development of “potential breakthrough ideas” in foodborne pathogen detection—specifically, detecting Salmonella in fresh produce.
It sounds tantalizing, a utensil that alerts you if something’s wrong with the food you’re about to eat. That’s the pitch made by Chinese search engine company Baidu—that nation’s equivalent of Google—about its new prototype “smart chopsticks.” Named “Kuaisou,” the prototype version of the chopsticks can allegedly identify the quality of cooking oil, a big issue in China, where smaller restaurants often use cheaper oil dredged from sewers and...
Investigators at the Agricultural Research Service and almond industry in California have developed a new attractant to help almond growers monitor populations of the navel orangeworm moth. The attractant can be used to determine moth numbers during orchard treatments that are intended to disrupt the mating cycle of the moth or used as a monitoring tool during normal orchard operations.
The FDA has completed a chemical safety assessment review focusing on the scientific capacity, efficiency, and management of its chemical safety resources. As a result of the review within CFSAN and the Center for Veterinary Medicine, the agency will update the FDA’s Toxicological Principles for the Safety Assessment of Food Ingredients (the so-called “Redbook”), the guidance document used primarily by CFSAN for evaluation of human food products.
