How do commercially available treatments handle Salmonella in feed? For those ready to take action, how should producers evalua
Welcome to Modern Agriculture!
Salmonella, a rod-shaped bacteria, is the cause of typhoid fever, but with typhoid eradicated from much of the world, it’s now best known for causing foodborne illness. The CDC notes that it causes over a million illnesses in the United States each year, as well as about 380 deaths. Though it’s often associated with raw chicken, it’s actually present in a wide variety of food items, from chocolate to spinach. One major reason it’s so pervasive is that it remains a chore to detect.
The main methods for detecting salmonella involve taking a sample and creating favorable conditions in a lab environment for salmonella to grow and reproduce. It’s not hard or expensive, really, but it is extremely time-consuming, taking anywhere from 48 hours to a week to confirm results. That’s a huge problem: Waiting for test results can be prohibitively expensive for producers and retailers, and dangerous for consumers. But a new method could help.
Last week, the FDA announced the winners of its 2014 Food Safety Challenge, a contest for new, innovative techniques for testing and solving problems of food safety. The $300,000 prize went to a team from Purdue University, who, according to the FDA’s site, developed a “physical method for concentrating Salmonella to detectable levels using automated microfiltration, which could decrease sample preparation time from 24-48 hours to a range of two to three hours.”
The runner-up prize of $100,000 went to Pronucleotein Inc, a company from San Antonio, for yet another pathogen detection device: this one a handheld scanner that uses DNA strands tagged with magnets to color pathogens, which light up under fluorescence.

Food borne diseases & global scenario: Up to 30% of the population in industrialized countries may be affected by food-borne illness each year and the problems are likely to be even more serious in developing countries. The global incidence of food-borne disease is difficult to estimate, but in 2005 it was estimated that 2.2 million people, including 1.8 million children died from diarrheal diseases. Microbiological hazards represent 93% of the incidents of food-borne illness and are the maj
Rhaphidophora Decursiva is one of the most sought-after varieties today. This is a scarce plant you won’t often find in nurseries or garden centers. Even though the plant grows flowers, it is usually cultivated for the stunning foliage that changes in shape and size as the plant matures. This plant is easy to grow when you make sure it has the perfect conditions. This guide gives the home gardener all the information necessary to ensure consistent Rhaphidophora Decursiva growth. What is Rh
There is a mistaken belief that Salmonella is transmitted to people primarily through dirty egg shells when, in fact, most cases of the illness are the result of an egg that was infected with Salmonella inside the hen’s ovary. Probiotics given to baby chicks reduces the risk of Salmonella in eggs and disease later in life. WHAT ARE PROBIOTICS? Probiotics are live, nonpathogenic bacteria that contribute to the health and balance of the intestinal tract. The
