Independent Toxicologists Issue Warning: We Object to the Claim That Chemical Dispersants Have A Low Potential For Accumulating in Marine Life and Do Not Pose an Environmental Health Concern

/PRNewswire/ -- Attorney Stuart H. Smith, representing the United Commercial Fishermen's Association, the Louisiana Environmental Action Network, public and private entities, and citizens harmed by the BP oil catastrophe, today issued this statement:

"Independent analysis by toxicologists dispute FDA claims made in the last few days that chemical dispersants used by BP during the oil catastrophe may not accumulate in marine animals.

"In fact, in a full report by Dr. Bill Sawyer released today, there is a grave problem caused by dispersants, due to the fact that these were used in deep waters and on such a vast scale.

"Studies of other spills show that the toxic components of crude oil 'bio-accumulate' into the food chain and become highly toxic to marine reproduction, even when dispersants are applied at the surface and the chemical toxins may be sufficiently diluted over time to pose only minimal risks.

"However, BP's use of dispersants deep underwater in the Gulf, and on such a vast scale, represents the first time dispersants have been used in this manner. The greatly-reduced biodegradation in the DEEPWATER HORIZON case, resulting from lack of sunlight, extreme cold temperatures at 5,000 feet, and other environmental factors significantly reduce the rate at which the dispersed crude components are degraded.

"Eight months would be required to remove 96 percent of the petroleum under ideal conditions, thus we can only assume what remains in the Gulf waters will be a 'toxic soup' of chemicals for the foreseeable future, due to the worst-case scenario which has unfolded.

"The most potentially dangerous of the components in the Gulf's toxic soup are 'polynuclear aromatic hydrocarbons' (PAHs), dangerous cancer-causing chemicals which slowly break down after being ingested by marine life, persist in marine organisms and can be passed to both humans and other wildlife through consumption.

"PAHs are not contained within the dispersants used, but rather, have been extracted from the BP crude and suspended in the water column via dispersant use.

"It must also be noted that the deep water National Oceanic and Atmospheric Administration Weatherbird analyses and our own near shore water, tunicate and beach samples have revealed a consistent pattern of dispersant-induced C19-C36 hydrocarbons and PAHs. Unfortunately, these specific PAHs are of the most toxic variety."

Don't eat a plant unless you can identify it

During summer, children are outside more, and the vibrant colors and smells of blooming flowers might lead them to take a little taste of a plant. This can be dangerous.

The Georgia Poison Control Center often receives questions about the dangers of mushrooms or houseplants, said Gaylord Lopez, the center’s director. But when someone calls about the toxicity of any plant, the answers to a series of questions determine how much exposure someone has had to the plant. The information is then compared to a plant database to see if signs or symptoms match the toxicity.

Lopez advises homeowners to identify the plants in their landscape and label them for easy identification. This information can prove life-saving if the plant is ever eaten.

“Most plant ingestions are by children, accidental, and in small quantities of only a couple of berries or leaves,” he said. Poison control operators advise callers on how to respond based on how much was eaten and which parts of the plant were swallowed. If someone eats high quantities of any plant, hospitalization may be required.

University of Georgia Cooperative Extension horticulturist Gary Wade says there are several poisonous plants in home landscapes.

“Most people don’t commonly eat leaves from plants in their landscape, but you never know when young children or playful teenagers will grab a few leaves and put them in their mouths, becoming nauseous or developing symptoms similar to food poisoning,” Wade said. “Furthermore, culinary experts use the flowers of nasturtiums and pansies in salads and as garnishes, but this does not mean that all flowers are edible.”

A few common landscape plants that contain toxic compounds capable of causing flu-like symptoms when eaten are azaleas, mountain laurel and rhododendron. Their leaves, stems, flowers and even their pollen contain andromedotoxin, which can cause headache, nausea and respiratory problems. Oakleaf hydrangeas have the compound hydragin in their leaves and buds. When eaten, these plant parts can cause stomach ache and diarrhea.

Ornamental cherries, including the cultivars Yoshino, Okame and Kwansan, are popular landscape plants. Their leaves, stems and seeds contain cyanogenic glycoside, a compound known to cause respiratory problems, dizziness and convulsions when eaten.

Wisteria pods and seeds contain a glycoside called wisterin that causes stomach ache, nausea, vomiting and diarrhea when eaten.

Angel’s Trumpet has become a popular plant in landscapes in recent years. Unfortunately, all parts of the plant contain tropane alkaloids, which cause headaches, convulsions and severe respiratory problems when swallowed.

“People should not stop planting these plants. They just need to be aware of their toxic properties when ingested and should be cautious when allowing young children, or even pets, to play around them,” Wade said. “The word poisonous does not mean deadly. The severity of the symptoms depends on the amount eaten and the plant part eaten.”

While poisonous plants are inconvenient to people, the toxins do serve a purpose to the plant. They are defense mechanisms plants use as protection from predators such as insects and bacteria. Plant poisons are so successful at keeping insects away that several early pesticides were mimics of naturally-
occurring chemicals of poisonous plants, said Matthew Chappell, a UGA Extension horticulturist.

“There is a small percentage of harmful poisonous plants if eaten, however, people need to be aware of the dangers of eating poisonous plants. If someone wants to eat a plant in the landscape they must be well versed in keying and identifying plants beforehand,” Chappell said. “If you are not a plant expert and would like to eat something in your landscape, call your local Extension office and ask them to identify the plant for you.”

For more information on poisonous plants around the home, see UGA Extension circular 957, Poisonous Plants in the Landscape, available on-line at http://pubs.caes.uga.edu/caespubs/pubs/PDF/C957.pdf.

U.S. Workers Risking Injury by Not Wearing Required Safety Equipment

/PRNewswire/ -- Nearly all of the safety professionals in a survey released today said that workers in their organizations had at some point failed to wear the necessary safety equipment while on the job.

An exceedingly high 98 percent of respondents who attended the recent American Society of Safety Engineers (ASSE) show in Baltimore answered "yes" when asked if they had observed workers not wearing safety equipment when they should have been, according to the survey, which was conducted by Kimberly-Clark Professional.

To make matters worse, 30 percent of these respondents said this had happened on numerous occasions. Given this, it's not surprising that worker compliance with personal protective equipment (PPE) protocols was cited as the top workplace safety issue by all survey respondents.

These findings are in keeping with results from surveys of safety professionals, conducted by Kimberly-Clark Professional at the National Safety Council (NSC) Congress in 2008, 2007 and 2006. Those surveys also found high levels of noncompliance with PPE protocols -- 89 percent in 2008, 87 percent in 2007 and 85 percent in 2006.

"Increasingly high noncompliance with PPE protocols is an alarming trend and a serious threat to worker health and safety," said Gina Tsiropoulos, manufacturing segment marketing manager for Kimberly-Clark Professional. "Whether this is a result of economic conditions, a flawed approach to safety programs, younger workers who are more inclined to take greater risks, or some other reason, it's essential that workers wear PPE when it is required. PPE protects workers against injury, but it will not work if workers fail to use it and use it properly."

It's no wonder then that three-quarters of respondents chose workplace accidents and injuries in response to the question: "What is most likely to keep you up at night?" Potential exposure because of noncompliance with PPE protocols was second, at 13 percent, while fear of a global pandemic and its impact on the workforce was a distant third, cited by only 8 percent of respondents.

Most Challenging PPE

When it comes to compliance with PPE use protocols, eye protection was found to be the "most challenging" PPE category, according to 42 percent of respondents, a disturbing though not unexpected finding considering that nearly three out of five workers who experienced eye injuries were found not to be wearing eye protection at the time of the accident or were wearing the wrong kind of eye protection for the job.(1) Add to this the facts that about 2,000 U.S. workers each day have a job-related eye injury that requires medical treatment(2) and that thousands are blinded each year from work-related eye injuries that could have been prevented(3) and the magnitude of the problem becomes clear.

The next highest category for noncompliance was hearing protection, also disturbing since occupational noise-induced hearing loss is 100 percent preventable when proper preventative measures are implemented. It was followed by gloves and head protection.

While the reasons for PPE noncompliance were varied, the biggest complaint was that it was "uncomfortable," selected by 40 percent of respondents, followed by:

-- Too hot
-- Not available near the work task
-- Poor fit
-- Unattractive looking


When asked what they had done or intended to do to improve compliance levels, these safety professionals' top choice was to improve existing education and training programs. This was followed by:

-- Increased monitoring of employees
-- Purchasing more comfortable PPE
-- Tying compliance to individual performance evaluations
-- Purchasing more stylish PPE
-- Developing incentive programs to encourage greater PPE compliance

How can Suppliers Help?

The issue of PPE comfort came to the fore again when safety professionals were asked what suppliers could do to improve their offerings. The number one selection was to "provide more comfortable PPE," followed by:

-- Providing more instruction on the proper use of PPE
-- Reducing prices
-- Providing greater size selection
-- Offering more stylish PPE

PPE of the Future

When safety professionals were asked about their visions for the future of PPE, fit, comfort and style took precedence. Forty-two percent of respondents said they would like to see PPE that automatically adjusts to fit different body types, hands, heads, faces, etc. Next was PPE with customizable style and design options, so that workers could select PPE based on their own individual tastes and safety requirements (32 percent). This was followed by PPE designed with integrated climate-control features, providing cooling or warmth as needed (15 percent).

The impact of customization and style on PPE compliance was further underscored by the response to another question. When asked if customizable or individualized style and design options would help increase PPE compliance, 87 percent of respondents said that it would.

'Toxic Towels'

Safety professionals were also asked about another area of concern -- the potential health and safety issues for workers posed by oil, grease, heavy metal residues or toxic elements on re-usable Rental Shop Towels. Sixty percent said they were disturbed by these hazards, with 20 percent of these respondents reporting they were "very concerned."

Worries about the risks to workers from "toxic towels" were the chief reason why safety professionals said they would switch to disposable wiping solutions from re-usable rental shop towels. What was the second most important reason for a potential change? A closed-loop solution that converts used disposable wipers to energy and diverts them from landfills. Not surprising, given the increased emphasis on environmental responsibility in manufacturing.

"Manufacturing facilities today are focused now more than ever before on conserving natural resources and reducing waste," said Tsiropoulos. "So a closed-loop solution for used wipers is a very appealing option."

Survey Methodology

The survey of 132 attendees at the American Society of Safety Engineers (ASSE) show in Baltimore, Md., was conducted via the Internet between June 9 and 13, 2010. All survey respondents said they were responsible for purchasing, selecting or influencing the purchase or selection of Personal Protective Equipment (PPE) or industrial wiping solutions. Ninety percent were safety directors or managers, while the other 10 percent were industrial hygienists, facilities or general managers, or held other positions. They were employed in the following fields: chemical/plastics manufacturing; construction/utilities; computer, electronics and electrical product manufacturing; food processing; metal manufacturing; transpiration equipment manufacturing or other fields.

FDA Warns of Salmonella Risk From Frozen Rodents Fed to Reptiles

/PRNewswire/ -- The U.S. Food and Drug Administration is warning U.S. and international customers who may have purchased frozen mice from Biggers and Callaham LLC, doing business as MiceDirect, that these products, which are used as food for reptiles, have the potential to be contaminated with Salmonella.

Because children, the elderly, and individuals with weakened immune systems are particularly at risk for salmonellosis, they should avoid handling either frozen rodents used as reptile food or reptiles. Children 5 years and under should not handle either frozen rodents used as reptile food or reptiles.

After handling either frozen rodents used as reptile food or reptiles themselves, individuals should thoroughly wash their hands with soap and water and use a disinfectant to thoroughly clean any surfaces that have been in contact with frozen rodents.

The FDA is actively investigating positive Salmonella findings in frozen mice and environmental samples taken at the company's Cleveland, Ga. plant. After being informed of the positive samples, Biggers and Callaham voluntarily recalled all frozen mice, rats and chicks purchased between May 2009 and July 23, 2010. The frozen reptile feed was distributed in all states, except Hawaii, through pet stores and by mail order and direct delivery.

On Aug. 2, 2010, the Centers for Disease Control and Prevention (CDC) reported that 34 human illnesses in 17 states were associated with handling frozen rodents used for reptile food sourced from Biggers and Callaham. In general, snakes and other reptiles can harbor many strains of Salmonella for several years, but still appear healthy.

Frozen reptile feed was shipped in plastic bags with the following product codes M-SP100, M-P100, M-PF100, M-F100, M-H100, M-W50, M-A50, M-JA25, R-P100, R-F50, R-PUP50, R-W50, R-S50, R-M20, R-L10,R-J5, R-C5, R-M3 followed by E9, F9, G9, H9, I9, J9, K9, L9 or A10, B10, C10, D10, E10, F10, G10 and whole frozen chicks in 25 count bags.

The FDA advises customers with the contaminated product to place it in a sealed container in the trash so that no children, pets, or other animals, such as wildlife, may be able to reach it.

Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. People infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting, and abdominal pain. Most people recover from Salmonella infections within four to seven days without treatment. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses, such as arterial infections (infected aneurysms), infection of the lining of the heart, and arthritis.

FDA Warns Consumers of Serious Harm from Drinking Miracle Mineral Solution (MMS)

/PRNewswire/ -- The U.S. Food and Drug Administration is warning consumers not to take Miracle Mineral Solution, an oral liquid solution also known as "Miracle Mineral Supplement" or "MMS." The product, when used as directed, produces an industrial bleach that can cause serious harm to health.

The FDA has received several reports of health injuries from consumers using this product, including severe nausea, vomiting, and life-threatening low blood pressure from dehydration.

Consumers who have MMS should stop using it immediately and throw it away.

MMS is distributed on Internet sites and online auctions by multiple independent distributors. Although the products share the MMS name, the look of the labeling may vary.

The product instructs consumers to mix the 28 percent sodium chlorite solution with an acid such as citrus juice. This mixture produces chlorine dioxide, a potent bleach used for stripping textiles and industrial water treatment. High oral doses of this bleach, such as those recommended in the labeling, can cause nausea, vomiting, diarrhea, and symptoms of severe dehydration.

MMS claims to treat multiple unrelated diseases, including HIV, hepatitis, the H1N1 flu virus, common colds, acne, cancer, and other conditions. The FDA is not aware of any research that MMS is effective in treating any of these conditions. MMS also poses a significant health risk to consumers who may choose to use this product for self-treatment instead of seeking FDA-approved treatments for these conditions.

The FDA continues to investigate and may pursue civil or criminal enforcement actions as appropriate to protect the public from this potentially dangerous product.

The FDA advises consumers who have experienced any negative side effects from MMS to consult a health care professional as soon as possible and to discard the product. Consumers and health care professionals should report adverse events to the FDA's MedWatch program at 800-FDA-1088 or online at www.fda.gov/medwatch/report.htm.

FDA Advisory: Avoid Unintentional Exposure of Children and Pets to Evamist

/PRNewswire/ -- The U.S. Food and Drug Administration is warning that inadvertent exposure to Evamist through skin contact with patients using this product has the potential for adverse effects in children and pets.

Evamist contains estradiol, an estrogen hormone, and is used in women to reduce hot flashes during menopause. The drug is sprayed on the skin between the elbow and wrist, on the inside of the forearm. The FDA currently is reviewing reports of adverse events in children and pets who were inadvertently exposed to this topical estrogen product.

"Women using Evamist need to be aware of the potential risks to children who come in contact with the area of skin where this drug is applied," said Julie Beitz, M.D., director of the FDA's Office of Drug Evaluation III. "It is important that people know to keep both children and pets away from the product to minimize exposure."

Evamist was FDA approved in 2007. From July 2007 to June 2010, FDA received eight post-marketing cases of unintended exposure to Evamist in children ages 3 years to 5 years. Adverse events reported in unintentionally exposed children include premature puberty, nipple swelling and breast development in females, and breast enlargement in males. Since 2007, two reports of secondary exposure to Evamist in dogs also have been received by FDA's Center for Veterinary Medicine. Pets exposed to Evamist may exhibit signs such as mammary/nipple enlargement and vulvar swelling.

Patients using Evamist should not allow children to make contact with the area of the arm where Evamist is sprayed and should wash the child's skin with soap and water as soon as possible if contact does occur. Pets also should not be allowed to lick or touch the arm where Evamist is sprayed as small pets may be especially sensitive to the estrogen in this product. If direct contact with the arm where Evamist was sprayed cannot be avoided, it is recommended that women wear a garment that covers the area where the drug was applied.

At this time, it is unknown whether unintended exposure can occur with other topical estrogen products. The FDA is continuing to review adverse event reports and evaluate ways to reduce unintended exposures to these products.

Consumers and health care professionals should report any side effects from Evamist by using the FDA's MedWatch Adverse Event Reporting program at www.fda.gov/MedWatch or by calling 800-332-1088.

Eye Strain, Dry Eyes, Fatigue and Headaches Associated With Those Spending More Than Four Hours in Front of Digital Devices

/PRNewswire/ -- Eye strain, fatigue and headaches are common indicators that your digital devices - including computer monitors, smart phones and video games - might be causing you discomfort.

According to recent research with VSP Vision Care eye doctors, 33 percent reported that nearly one third or more of their patients suffer from symptoms of Computer Vision Syndrome or digital device-related vision problems. The most common symptoms of patients suffering from Computer Vision Syndrome include eye strain (82 percent), dry or irritated eyes (74 percent), fatigue (70 percent) and headaches (61 percent). Yet, two in three eye doctors report 20 percent or fewer of their patients even know what Computer Vision Syndrome is, showing a low level of understanding of the condition.

Computer Vision Syndrome is a serious condition that can have a major impact on the well-being, work productivity and learning capacity. As six hours is the average time spent in front of a digital device, American workers alone are spending in excess of 200 billion hours a year in front of a digital screen.

"Computer Vision Syndrome is a major problem for Americans," said Dr. Nate Bonilla-Warford, VSP provider. "For professionals with this condition, work productivity can decrease by as much as 20 percent. We are seeing patients uncomfortable in the workplace with neck pain, headaches, eye strain, blurred vision, etc. that could easily be avoided. It's important for people to discuss their digital usage with their eye doctor and make sure they are getting annual eye exams."

VSP Vision Care recommends the following tips to help lessen the symptoms of computer-related eye strain:

1. Blink Often: When looking at a computer or hand-held digital device,
it's common for you to blink two to three times less than you normally
would. This can lead to "dry eye." Blinking bathes your eyes in
tears, and tears are naturally therapeutic for the eyes.
2. The 20/20/20 Rule: When spending long periods in front of a digital
device, every 20 minutes, spend 20 seconds looking at something 20 feet
away to allow your eyes to rest.
3. Ensure Proper Lighting: Poor lighting often causes eye strain. To help
ease the strain on your eyes, keep bright lighting overhead to a
minimum and position your desk lamp to shine on your desk, and not at
you. Position your computer screen in a way that reduces reflections
and glare from windows or overhead lights.


"Today, digital device eye strain is the number one computer-related complaint ahead of carpal-tunnel, neck and back pain," Dr. Bonilla-Warford continued. "Eye doctors are trained to help patients mitigate the symptoms of Computer Vision Syndrome, and can even offer computer vision glasses, which are prescribed glasses that provide the optimal lens power for viewing your computer screen at the correct distance, without the need for excessive focusing or squinting."
