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. Schneider, Rachael Silverberg, Alexandra Chang and Renée Goodrich Schneider, and published by the UF Department of Food Science and Human Nutrition, December 2014.

Selective Antibiotic Treatment for Dairy Cow Mastitis

Figure 1. Bi-plate of Minnesota Easy Culture System II. (Top: Factor agar. Bottom: MacConkey agar.)Mastitis is the most common disease in dairy cattle and is estimated to cost dairy farmers $179 a case. When farmers detect clinical mastitis, they usually take immediate action with antibiotics; but many cases either do not need antimicrobial treatment, resolve without treatment, or are not effectively treated by the antimicrobial used. A selective treatment approach can be more effective. This two-step strategy involves first identifying the pathogen, then deciding on a treatment — this would decrease the use of antimicrobials as well as treatment-associated costs for the farmer.

The Facts about Mothballs

Figure 1. Mothballs are formulated as solids.Mothballs, moth flakes, crystals, and bars are insecticides that are formulated as solids. Naphthalene and paradichlorobenzene, the active ingredients in mothballs, are registered as pesticides. As such, their label directions carry the force of the law, including use intent and the sites where they may legally be used. They can harm people, pets, or wildlife that may touch or eat the mothballs or that may breathe the vapors.

Carinata Production in Florida

Figure 1. From field to flightBrassica carinata is a promising oilseed crop with great potential for profitable cultivation in Florida. Its high oil content and favorable fatty acid profile make it suitable for the biofuel industry, especially as a biojet fuel. The UF/IFAS North Florida Research and Education Center (NFREC) in Quincy, Florida, has been working to identify advanced carinata genotypes that are high yielding (seed and oil), disease resistant, early maturing, and adapted to Florida. The work at NFREC is being done in conjunction with Agrisoma Biosciences Inc., a crop company that has the world’s largest collection of carinata germplasm. This 6-page fact sheet’s “Agronomic Management” section provides recommendations resulting from NFREC’s research. was written by C. M. Bliss, R. Seepaul, D. L. Wright, J. J. Marois, R. Leon, N.

Techniques for Melon Grafting

Grafting as a cultural practice for controlling soilborne diseases and improving abiotic stress tolerance has been widely used in vegetable production in many areas of Asia and Europe. Interest in vegetable grafting has been growing in the United States in recent years, as well. Cost, along with the desire to customize scion cultivars and the need to produce organic transplants, has led many small and organic growers to choose to graft plants by themselves. To help growers who are interested in grafting melon plants achieve a high graft survival rate, this 5-page fact sheet introduces commonly used grafting techniques and their application in specific circumstances. Written by Wenjing Guan and Xin Zhao, and published by the UF Department of Horticultural Sciences, December 2014.

Best Management Practices for Siting Honey Bee Colonies: Good Neighbor Guidelines

Figure 1. Backyard beekeeping set-up using hives with movable frames. Beekeeper has not exceeded the number of hives on this parcel. Hives are facing the fence, which acts as a flyway barrier.Keeping honey bees requires responsible management so that the bees do not become a nuisance. Additionally, the presence of Africanized honey bees in Florida places more pressure on beekeepers to maintain their colonies properly. This 3-page fact sheet is a reference for honey bee management in Florida, with emphasis on siting apiaries in sensitive locations, in order to promote harmonious cooperation between beekeepers, neighbors, and landowners.

Genetically Modified Food

Closeup of cornA food is considered genetically modified when its genetic makeup is altered in some way as a result of the use of recombinant DNA biotechnological procedures. These changes result in the expression of attributes not found in the original. Examples include delayed-ripening tomatoes and pest-resistant or herbicide-tolerant crops. Genetic modification can be used to improve crop yields, reduce insecticide use, or increase the nutritional value of foods. This 5-page fact sheet answers questions consumers might have about genetically modified food. Written by Keith R.

Spousal Individual Retirement Accounts

Figure 1. Identify areas in your finances where you may incur unexpected costs, such as medical emergencies, car accidents, or other events. By having a plan to deal with these situations, you can save money in the long run. Credit: HuntstockA spouse who stays at home to take care of children or other dependents is likely to have reduced Social Security benefits and will not have access to a workplace retirement plan. So a spousal Individual Retirement Account (IRA) can be an important step to enabling retirement security. An IRA is a tax-advantaged way to accumulate money for retirement. In order to contribute to an IRA you must have taxable compensation. But if your spouse has taxable compensation and you file a joint return, then you can fund an IRA.

Is My Tree Safe? Recognizing Conditions that Increase the Likelihood of Tree Failure

Figure 1. Dead branches pose threat to targets.Urban trees provide shade and beauty and the urban forest as a whole provides a wealth of benefits to neighborhoods and residents. But stresses from the urban environment may lead to problems that pose an unacceptable safety risk to people and property. It is a landowner’s responsibility to ensure that the trees on their property are safe. A key step in reducing the potential for tree-related injury or property damage is learning to identify common tree defects associated with increased risk of failure.
