Survival of Foodborne Pathogens on Berries
Fresh and frozen berries are popular foods. When berries are picked for fresh consumption, they are usually packed directly without washing because they are highly perishable. There is typically no “kill step” that would eliminate pathogens on fresh or frozen berries. Foodborne illness outbreaks have been associated with the consumption of fresh or frozen berries that were contaminated with pathogenic viruses, parasites, or bacteria. Contamination can occur before or during harvest or during final preparation. This 11-page fact sheet was written by Mary Palumbo, Linda J. Harris, and Michelle D. Danyluk, and published by the UF Department of Food Science and Human Nutrition, November 2014.

The Food Safety Modernization Act of 2011 – Proposed Rule for Preventive Controls for Human Food
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. This 5-page fact sheet was written by Soohyoun Ahn, Keith R. Schneider, Michelle D. Danyluk, and Renee Goodrich-Schneider, and published by the UF Department of Food Science and Human Nutrition, April 2014.

Datos sobre los antioxidantes
Nuestro cuerpo está constituido de células. Dentro de éstas ocurren constantemente reacciones químicas, que se conocen colectivamente como metabolismo. Estas reacciones son necesarias para la vida, pero algunas veces crean radicales libres. Los radicales libres son moléculas altamente reactivas que pueden iniciar reacciones dañinas en cadena en nuestras células. Esto se conoce como estrés oxidativo. Diversas investigaciones relacionan el estrés oxidativo con muchas enfermedades: artritis, enfermedades de los pulmones (como enfisema), enfermedades del corazón, enfermedad cerebro vascular, ulceras, hipertensión, Parkinson y Altzheimer, distrofia muscular y otras. El estrés oxidativo también contribuye al proceso normal de envejecimiento. This 3-page fact sheet is the Spanish language version of Facts about Antioxidants, written by Kaitlin G.

Datos sobre los Carbohidratos
Los carbohidratos, grasas y proteínas son los tres nutrientes que proveen energía (calorías). Sin embargo, los carbohidratos como los almidones y azúcares son la fuente más importante y principal de energía. Durante la digestión, el almidón se rompe en azúcares (glucosa). Los carbohidratos en forma de glucosa proveen energía a las células, tejidos y órganos para llevar a cabo las actividades diarías. Alguna glucosa se almacena en el hígado y células de los músculos para usarla cuando se requiera. Los niños necesitan carbohidratos para el crecimiento y los adultos necesitan para mantener el peso.

Dealing with Food Allergies
A food allergy is an immune system reaction that happens after a person consumes what is normally considered a safe food. Food allergies occur more often in children than in adults: 4%–8% of those aged 4 or under and about 2% of adults are affected. Allergic reactions from food have led to over 20,000 emergency room visits per year. Annually, between 150 and 200 fatalities associated with food allergic reactions occur in the United States.

Facts about Antioxidants
Our bodies are made up of cells. Chemical reactions necessary for life are constantly occurring inside our cells, and sometimes they create free radicals — highly reactive molecules that can initiate damaging chain reactions known as oxidative stress.
Antioxidants can inactivate free radicals and protect our cells from oxidative stress and the damage it causes. Antioxidants also can help our immune system defend against bacteria, fungi, viruses, and some cancers. The body produces some of its own antioxidants, but eating a plant-based diet increases the level of antioxidants in our bodies. This 3-page fact sheet was written by Kaitlin G. Clark and Wendy J. Dahl, and published by the UF Department of Food Science and Human Nutrition, February 2014.

Facts about Carbohydrate
Carbohydrate, fat, and protein are the three nutrients that provide energy (calories). However, carbohydrate from starch and sugars is our main and most important source of energy. During digestion, starch is broken down to sugar (glucose). Carbohydrate in the form of glucose provides energy to cells, tissues, and organs to carry out daily activities. Some glucose is stored in the liver and muscle cells for later use when required. Children need carbohydrate for growth, and adults need carbohydrate to maintain their weight.
