Lightning Safety for Florida Agriculture Workers

Lightning streaking across a sky.

Lightning is a common occurrence in Florida. Although lightning kills only about 10% of the people it strikes, it can cause physical and mental complications that victims must face for the rest of their lives. Agriculture workers need to have a good working knowledge of lightning, its effects, and ways to protect others and themselves from this potentially life-threatening hazard. This new 4-page document discusses types of lightning, outdoor safety for farm workers, lightning medical aid, and regulations for employers.

El decreto de Modernización de la Seguridad Alimentaria (FSMA por sus siglas en inglés) fue firmado en Enero del 2011. Dicho documento intenta cambiar el enfoque de la seguridad alimentaria hacia prevención en lugar de reacción ante eventos relacionados con alimentos. Determinar si un peligro requiere un control preventivo depende de la frecuencia y la gravedad del peligro, el cual varía de acuerdo a la instalación y la especie alimentada. This 5-page fact sheet is the Spanish version of EDIS document AN344, Common Hazards to Consider During Manufacturing of Feeds for Horses. Written by Ana Margarita Arias, Taylor N.

Horses are uniquely sensitive to fumonisin and ionophores compared to other livestock species. Facilities, particularly mixed-species feed facilities, need to ensure CGMPs, SOPs, and possibly preventive controls are implemented to address those concerns in addition to more general hazards. This 5-page fact sheet discusses common biological, chemical, and physical hazards in horse feeds as well as methods of prevention. Written by Jason M. Scheffler, Taylor N.

Frost Damage of Carinata Grown in the Southeastern US

More severe cold damage of carinata during early bolting. This level of damage is expected to reduce stands and yield. Note that aboveground tissue was severely affected, but neither the growing points nor roots died. This field generally grew back from the growing point, but could have resprouted at the crown if the damage was more severe. UF/IFAS West Florida Research and Education Center, Jay, FL.

Brassica carinata is an annual oilseed crop used for the commercial production of jet fuel. One of the challenges to commercialization of this crop in the southeastern United States has been frost damage. This 4-page fact sheet discusses symptomology and ways to minimize risk of frost damage to carinata. Written by Michael J.

El Zika, un Virus Transmitido por Mosquitos

aegypti_albo2 blrrb
Zika es un virus transmitido por mosquitos que se ha esparcido recientemente en regiones tropicales y ha causado epidemias, especialmente durante los últimos 8 o 9 años. En su ámbito nativo en África Occidental y Uganda, el virus se mantiene en los bosques, circulando entre mosquitos que viven en huecos de árboles y primates arbóreos; las infecciones de humanos se consideran incidentales y de poca importancia médica. Una cepa del virus que se implicó en brotes en Polinesia Francesa emergió en el Norte de Brasil en el 2015 y causó gran consternación debido a la alta incidencia de microcefalia en bebes nacidos de madres que fueron infectadas con el virus durante la gestación. Transmisión local, principalmente por el mosquito de la fiebre amarilla Aedes aegypti, ha sido documentada en la mayoría de los países tropicales de las Américas, pero aún no se ha detectado en Los Estados Unidos Continentales. Los síntomas de la infección incluyen, salpullido, dolor de cabeza, fiebre, dolor muscular y en las coyunturas, conjuntivitis, y malestar general.
This 7-page fact sheet written by J. R. Rey, L. P. Lounibos, B. W. Alto, N. D. Burkett-Cadena, C. C. Lord, C. T. Smartt, and C. R. Connelly and published by the Department of Entomology and Nematology is the Spanish language version of Zika, a Mosquito-Transmitted Virus and describes the Zika microbe, its mosquito hosts, and the disease it causes. A history of the virus and its migration are included, along with some details about the virus in the state of Florida and preventative measures people can take to avoid infection. The best way to avoid contracting Zika (and other mosquito-borne diseases) is not to get bitten in the first place. Take precautions to avoid mosquito bites.
