Blue-green algae alert issued for multiple Orange County lakes by Department of Health
With water sample testing underway, blue-green algae has the potential to produce toxins. Since environmental conditions can change at any time, it is important to exercise caution, even if the presence of toxins has not yet been confirmed.
Residents and visitors are advised to take the following precautions:
• Do not drink, swim, wade, use personal watercraft, or come into contact with waters where there is a visible bloom.
• Wash your skin and clothing with soap and water if you come into contact with algae, discolored water, or water that smells unpleasant.
• Keep pets and livestock away from the area to avoid contact with water. Waters where algae blooms are not safe for animals, so pets and livestock should use an alternative water source when algae blooms are present.
• Do not cook or clean dishes with water contaminated by algae blooms. Boiling the water will not eliminate toxins.
• Eating fillets from healthy fish caught in freshwater lakes experiencing blooms is safe. Rinse fish fillets with tap or bottled water, throw out the guts, and cook fish thoroughly.
• Do not eat shellfish in waters with algae blooms
What is Blue-Green Algae?
Blue-green algae are a type of bacteria that is common in Florida's freshwater environments. A bloom occurs when the rapid growth of algae leads to an accumulation of individual cells that discolor water and often produce floating mats that emit unpleasant odors.
Blue-green algae blooms can also appear as scum, foam, or paint on the surface of the water in various colors. To learn more about the appearance of algae blooms, visit Protecting Florida Together.
Is Blue-Green Algae Harmful?
Blue-green algae can produce toxins that can be harmful to humans and pets as well as ecosystems, including fish and other aquatic animals.
Sensitive individuals (e.g., children, the elderly, and the immunocompromised) may still be at risk even at low concentrations and should avoid any exposure.
If you have other health questions or concerns about blue-green algae, please call DOH-Orange at 407-723-5004.

Fecal indicator bacteria prompt water quality advisories at five Bay County beaches
PANAMA CITY— The Florida Department of Health in Bay County has issued water quality advisories for fecal indicator bacteria at five local beaches. The following locations are under advisories for high levels of enterococcus bacteria: Laguna Beach: 19440 Front Beach Road, Panama City Beach Panama City Beach City Pier: 16101 Front Beach Road, Panama City Beach Rick Seltzer Park: 7419 Thomas Drive, Panama City Beach Beach Drive: U.S. 98 West Beach Drive, Panama City Earl Gilbert Park: 6601 Oak Shore Drive, Parker The Department of Health is advising against entering the water at these locations. Advisories will remain in place until bacteria levels are below the accepted health standards. Meanwhile, Carl Gray Park in Panama City has had its Aug. 12 advisory lifted. Enterococci bacteria live in the digestive systems of mammals and can indicate fecal contamination in the water. The Environmental Protection Agency says leaky septic systems, stormwater runoff, effluent from wastewater treatment plants, discharge from boats and agricultural runoff are all sources of fecal indicator bacteria. The News Herald previously reported that aging wastewater infrastructure in Bay County can sometimes lead to sanitary sewer overflows, especially during extreme weather events. Enterococci bacteria aren't harmful, but their presence means that there could be pathogens present that are. Eating raw fish or shellfish from affected waters can also cause illness. According to the Florida Healthy Beaches Program, swimming in affected waters could lead to gastrointestinal disease, infections or rashes. Bay County issues guidance for ways local residents can help preserve water quality. They suggest that septic tanks should be pumped and inspected to prevent leakage every three to five years. Authorities also advise fertilizer be used sparingly and lawn chemicals be used with discretion. Fertilizer flows downstream and can cause algae blooms.

World's deadliest animal is probably outside your Florida home right now. Protection tips
What's the world's most dangerous animal? Hint: It's plentiful in Florida and no, it's not an alligator, shark or python. According to the Centers for Disease Control the deadliest animal in the world is the mosquito. "The mosquito kills more people than any other creature in the world," the CDC said, noting the flying nuisance spreads such diseases as malaria, dengue, West Nile, yellow fever, Zika and chikungunya. The Florida Department of Health said there are 80 types of mosquitoes in the state, many of which transmit diseases. The agency tracks mosquito-borne illnesses — known as arboviruses — acquired locally and those contracted by people with a history of travel. Here's what you should know, including how you can protect yourself and your family. Mosquito-borne illnesses confirmed in Florida and Palm Beach County so far this year The latest report from the Florida Department of Health has confirmed the following cases of mosquito-borne illnesses in the state between Jan. 1 through Aug. 2: West Nile Virus: 5 asymptomatic blood donors Escambia: 5 Chikungunya: 4 cases in those with travel history Broward: 2 Lake: 1 Miami-Dade: 1 Dengue: 122 cases in those with travel history; 7 cases in non-Florida residents Bay: 1 Brevard: 2 Broward: 10 Clay: 1 Collier: 2 Duval: 3 Escambia: 1 Hillsborough: 6 Lake: 3 Lee: 4 Manatee: 1 Marion: 1 Miami-Dade: 63 Okeechobee: 3 Orange: 6 Osceola: 2 Palm Beach; 5 Pasco: 1 Pinellas: 3 Polk: 1 St. Johns: 1 St. Lucie: 1 Volusia: 1 Denque acquired in Florida: 8 cases Brevard: 6 Miami-Dade: 2 Malaria: 28 cases in those with travel history; 9 in non-Florida residents Alachua: 1 Brevard: 1 Broward: 3 Collier: 1 Duval: 1 Hillsborough: 1 Lake: 1 Marion: 2 Miami-Dade: 4 Nassau: 2 Orange: 3 Palm Beach: 3 Polk: 2 St. Lucie: 2 Volusia: 1 What mosquito-borne diseases are tracked in Florida? The Florida Department of Health tracks travel- and locally acquired cases of the followed mosquito-borne diseases: West Nile fever and West Nile encephalitis Eastern equine encephalitis virus St. Louis encephalitis virus Dengue virus Chikungunya virus Zika virus California encephalitis group viruses Malaria Florida has more than 80 types of mosquitoes. Here are 5 'most wanted' The Florida Department of Health said there are more than 80 different species of mosquitoes in Florida, compared to about 3,500 species in the world. While not all of them cause disease, here are five the agency lists as "Florida's most wanted": Aedes aegypti, the yellow fever mosquito Larvae are found in water-holding objects found around the home and yard, such as flower vases, tires, toys, bottles, conch shells, cans, refrigerator drain pans, barrels, bromeliad plants, and other containers. Can be found in all of Florida except Panhandle counties. Diseases: Dengue, chikungunya, and Zika viruses. Aedes albopictus, the Asian tiger mosquito Larvae found in water-holding objects found around the home and yard, such as flower vases, tires, toys, bottles, cans, barrels, tree holes, bromeliad plants, and other containers. Found in all Florida counties. Diseases: Dngue, chikungunya, and Zika viruses. Culex quinquefasciatus, southern house mosquito Larvae are found in a variety of aquatic habitats, especially those with high organic content, including catch basins, ditches, containers, dairy lagoons, and others. Found in all Florida counties and are abundant throughout the state. Diseases: Dog heartworm, St. Louis encephalitis virus, West Nile virus. Aedes taeniorhynchus, Black salt marsh mosquito Larvae are found in salt marshes. Found in all Florida counties and are strong fliers that are major pests during summer and early fall. Disease: Dog heartworm. Psorophora ciliata, Gallinipper Larvae are found in ditches, containers, grassy pools, furrows of citrus groves, pasture areas. Found in all Florida counties. Diseases: None none. What attracts mosquitoes? While there's not much we can do about some conditions mosquitoes are attracted to — this is Florida — we should note mosquitoes are drawn to: Damp or humid areas Standing water Warm temperatures Dark, shady areas Carbon dioxide (your breath) Myth or magic? Do mosquito-repelling plants really work? Mosquitoes need standing water to lay their eggs. And they don't need much. Water in a bottle cap can provide an ideal breeding ground. Experts repeatedly encourage residents to empty flower pots, bird baths and any outdoor item that holds standing water — including bromeliads — to stop mosquitoes from breeding. Some residents share ideas to make outdoor living more bearable by selecting mosquito-repelling plants for their landscape, especially citronella and lavendar. But do they really work? 'Certain plants do contain mosquito-repelling compounds,' says Liah Continentino, environmental horticulture agent with University of Florida/IFAS Extension Monroe County. 'But unless you're extracting their oils and applying them like a spray, they're not doing much just sitting in your garden. 'Plants like eucalyptus, citronella, mint, basil, lavender and marigolds have oils that can deter mosquitoes. But the key word is 'oils.' These compounds need to be extracted and used in concentrated forms — like sprays — to be truly effective." In other words, mosquito-repelling plants are more myth than magic — at least when it comes to passive protection, UF said in a news release. So what can Florida residents do to minimize mosquitoes? Don't give up when it comes to enjoy Florida outdoor living. There are some things you can do and some do involve plants. Here are a few ideas: Reduce mosquito habitats 'This includes regularly emptying plant saucers, bird baths, pet water bowls and bromeliads, as well as any other water-holding plants. Refreshing bird baths and pet bowls with clean water several times a week and flushing bromeliad cups with a hose can help prevent larvae from developing,' said Jennifer Pelham, UF/IFAS urban horticulture agent and director of UF/IFAS Extension Martin County. Use plants in your landscape to attract mosquito predators "For dragonflies, which are highly effective mosquito hunters, they are drawn to native aquatic plants. For birds, include shrubs and trees that supply food, shelter and nesting areas,' said Lorna Bravo, urban horticulture agent with UF/IFAS Extension Broward County. Use fish to control larvae For water features that are permanent, such as ornamental ponds, UF/IFAS recommends adding mosquito-eating fish like Gambusia to naturally control larvae. Cover rain barrels with screens and refresh pet water bowls daily to prevent mosquito access. Encourage mosquito predators in your yard, including fish, dragonflies, fronts, birds and bats. What are the best mosquito repellents to use? According to the CDC, repellents with the following active ingredients "typically provide reasonably long-lasting protection": DEET Picaridin Oil of Lemon Eucalyptus or PMD "Products containing oil of lemon eucalyptus specifies that they should not to be used on children under the age of 3." IR3535 2-undecanone "Certain products containing permethrin are recommended for use on clothing, shoes, bed nets, and camping gear, and are registered with EPA for this use." Items that don't work to repel mosquitoes "There are many gimmicks for sale that do not work, so be an educated consumer and don't waste your money on impulse buys," the Florida Department of Health said. Some items that are not effective for reducing mosquitoes include: Mosquito plants Bug zappers Consumption of garlic, vitamin B, and bananas Repellent bracelets and wristbands Ultrasonic devices and cell phone apps Dragonfly mimics This article originally appeared on Palm Beach Post: Alligators aren't deadliest animal, mosquitos are. 80 types in Florida Solve the daily Crossword

NY must launch own probe into city's handling of deadly Harlem Legionnaires' outbreak, ex-Gov. Cuomo says
Gov. Kathy Hochul's administration must launch its own probe into New York City's handling of the deadly Legionnaires' disease outbreak in Harlem, her predecessor Andrew Cuomo said Wednesday. Cuomo — now running for mayor — was governor when a Legionnaires' outbreak hit The Bronx in 2015, resulting in 15 deaths and 120 hospitalizations. After hearing complaints from Bronx officials and residents, he ordered a state investigation that led to stricter rules involving testing cooling towers for the disease-causing bacteria Legionnela. 'Confidence in government is paramount, and New Yorkers deserve to know if the City followed its own rules to prevent this deadly outbreak,' Cuomo said in a statement.

Gaston 'The last time we confronted a Legionnaires' outbreak of this scale, we not only moved heaven and earth to stop it, we put in place tough new protocols to prevent it from happening again,' he said. 'With the City now serving as both the regulator and the landlord for many of the affected buildings, there is an inherent conflict of interest. Only an independent review can determine whether the right steps were taken – or whether City inaction made a bad situation worse.' Advertisement Some of the cooling towers that tested positive for Legionnella in the current outbreak are on city-owned buildings, including Harlem Hospital and the city Department of Health's Central Harlem Sexual Health Clinic on the same stretch of West 137th Street. 4 Cooling towers in Harem that tested positive for Legionnaires'.

There's an 'inherent conflict of interest' for the city to serve as both 'the regulator and the landlord' of the affected buildings, he said.

Rob Jejenich / NY Post Design At least five people have died and more than 100 others have been sickened with Legionnaires', according to city health officials. A state Health Department spokesperson told The Post on Tuesday that it was assisting city Health Department officials in addressing the outbreak. Advertisement 'DOH continues to work around the clock to support NYC's legionnaires response. As a result of this collaborative effort, exposure has been significantly reduced, with no new diagnoses since August 12, and all identified deficient cooling towers have been remediated. We are continuing to aggressively monitor the situation, and any New Yorker experiencing symptoms should seek medical treatment immediately,' the DOH spokesperson said. Hochul said the state was playing a 'supportive role,' adding, 'I'm concerned and that I know the city's all over this. If I didn't think so, I'd let you know.' The Rev. Al Sharpton, along with civil rights attorney Ben Crump, is unveiling a lawsuit Wednesday against a construction company that did work in Harlem Hospital and allegedly contributed to the outbreak.
