The Gables, Florida based company recently recalled nearly 60,000 cantaloupes after learning of the product’s link to the Salmonella outbreak.

The Outbreak

CDC is collaborating with public health officials in many states and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA/FSIS) to investigate a multistate outbreak of Escherichia coli O157:H7 infections. Investigators are using DNA analysis of E. coli O157:H7 bacteria obtained through diagnostic testing to identify cases of illness that may

A study, conducted by scientists at the University of Georgia in collaboration with scientists at Ohio State University and North Carolina State University, was recently published in the November 2010 issue of the Foodborne Pathogens and Disease Journal. The study suggests that the prevalence of fecal Salmonella and anti-microbial Salmonella is lower in certified-organic

3000 cases of 105-ounce canned pickled sliced beets have been voluntarily recalled by Lakeside Foods, Inc. of Manitowoc, Wisconsin due to a potential contamination with certain harmful organisms including Clostridium botulinum. The recall, announced yesterday, was issued because some cans of the company’s product may not have been fully processed, creating a breeding

A new studyis available online in the Oxford journal “Clinical Infectious Diseases” detailing the findings of an investigation into an outbreak of norovirus on a cruise ship in 2009.  Norovirus is the most common type of food-poisoning in the United States.  Usual symptoms of norovirus infection include nausea, vomiting, diarrhea, and abdominal pain. Headache and low-grade

Salmonella Illnesses

Symptoms of Salmonella gastroenteritis include diarrhea, abdominal cramps, fever, nausea, and/or vomiting. In mild cases diarrhea may be non-bloody, occur several times per day, and not be very voluminous; in severe cases it may be frequent, bloody and/or mucoid, and of high volume.  Complications of Salmonella infection can include sepsis, reactive arthritis, and post-infectious irritable bowel syndrome. 

Reactive Arthritis

The arthritis that can be caused by Salmonella infection affects the knees, ankles, and feet, causing pain and swelling. Wrists, fingers and other joints can be affected, though with less frequency. Patients with reactive arthritis commonly develop inflammation where the tendon attaches to the bone, a condition called enthesopathy. Some patients with reactive arhtritis also develop heel spurs, bony growths in the heel that cause chronic or long-lasting foot pain. Reactive arthritis can also affect the joints of the back and cause spondylitis, inflammation of the vertebrae in the spinal column. The duration of reactive arthritis symptoms can vary greatly. Most of the literature suggests that the majority of patients recover within a year. The condition, can, however, be permanent. One study found nearly 50 percent of patients with post dysenteric reactive arthritis continued to have symptoms roughly one year after onset (Inman, et al., 1998).

Post-Infectious Irritable Bowel Syndrome

 Irritable bowel syndrome (IBS) is one disorder in a spectrum of common functional gastrointestinal disorders. Symptoms of IBS can include constipation, diarrhea, alternating diarrhea and constipation, abdominal pain, urgency, bloating, straining at stools, and a sense of incomplete evacuation. The Rome III definition for IBS, which is widely accepted in the medical community, is recurrent abdominal pain or discomfort at least three days per month for at least three months, with at least two of the following symptoms also present: improvement of the pain or discomfort with defecation, a change in frequency of stools, or a change also in the form or appearance of stool.

The observation that the onset of IBS symptoms can be precipitated by gastrointestinal infection dates to the 1950s. Different studies have shown that 7-31% of individuals who have experienced an episode of infectious gastroenteritis, whether bacterial or viral, may develop symptoms of IBS.Continue Reading Salmonella, Cantaloupes, and Information
