Preventing Foodborne Illness: Cyclospora cayetanensis

This photomicrograph of a fresh stool sample, which had been prepared using a 10% formalin solution, and stained with modified acid-fast stain, revealed the presence of four Cyclospora cayetanensis oocysts in the field of view. Cyclospora cayetanensis is a microscopic, spore-forming, intestinal protozoan parasite and a known cause of the gastrointestinal infection cyclosporiasis, often referred to as “traveler’s diarrhea” for its prevalence among visitors to regions where the species is endemic. These organisms have a protective covering that makes them resistant to disinfectants and that gives Cyclospora the ability to survive outside of hosts for extended periods. The incidence of cyclosporiasis has been increasing worldwide, with several documented cases in the United States and Canada. This 4-page fact sheet was written by Keith R. Schneider, Rachael Silverberg, Susie Richardson, and Renée Goodrich Schneider, and published by the UF Department of Food Science and Human Nutrition, March 2015. (Photo: CDC/DPDx – Melanie Moser)

Preventing Foodborne Illness: Clostridium botulinum

photomicrographic view of a gentian violet-stained culture specimen revealing the presence of numerous Gram-positive Clostridium botulinum, formerly known as Bacillus botulinus, bacteria and bacterial endospores.Clostridium botulinum is ubiquitous in nature, often found in soil and water. The bacteria and spores alone do not cause disease, but they produce the botulinum toxin that causes botulism, a serious paralytic condition that can lead to death. Although it is one of the least common of the foodborne diseases, anyone is susceptible even with the ingestion of only a small amount of toxin present in contaminated food. Immunocompromised individuals, young children, and elderly individuals may suffer from more serious symptoms. This 6-page fact sheet was written by Keith R.

The Food Safety Modernization Act of 2011 – Proposed Rule for Preventive Controls for Human Food

President Barack Obama signs H.R. 2751, the “FDA Food Safety Modernization Act,” in the Oval Office, Jan. 4, 2011. (Official White House Photo by Pete Souza)The Food Safety Modernization Act (FSMA), which was signed into law by President Obama on January 4, 2011, is the most sweeping reform of food safety laws in more than 70 years since the enactment of the Federal Food, Drug and Cosmetic Act of 1938. High-profile foodborne outbreaks in the last decade and their impact on public health and the economy have exposed the need for a new, modern food safety system. FSMA aims to ensure the safety and security of the US food supply by focusing on preventing food safety problems rather than responding after they occur. This law provides the FDA with new enforcement authorities to achieve a higher rate of compliance with food safety standards and to respond better to problems.
