Rising ocean temperatures are leading to a rise in shellfish containing a potentially deadly toxin, according to new research. Domoic acid, a natural toxin produced from marine algae, can reach hazardous levels as ocean temperatures rise. The toxin accumulates in shellfish and fish to no ill-effects; however, in humans the toxin crosses the blood-brain barrier causing brain-damage or death at high doses.
Warmer waters off the west coast near Oregon and Washington have resulted in algae blooms so large they can be seen from outer-space. A team of experts from a NOAA associated with Oregon State University are developing new methods for tracking the blooms. "Using extensive time series of biological, chemical, and physical data, this study also created a climate-based risk analysis model which predicts where and when domoic acid in shellfish will likely exceed regulatory thresholds.”
This study may help determine if the increased ocean-climate variability will lead to wide-spread outbreaks of algae blooms. This data can be used to make public health decisions on crab and fish harvesting at particular times and locations of the year. These current blooms are largely a product of two natural weather processes, the El Niño effect and the Pacific Decadal Oscillation.
However, scientists warned that if ocean temperatures rise because of global warming, this could lead to an increase in the numbers of poisonous shellfish.

Home to the most renowned beaches in the US, Florida’s beautiful coastlines comes with its share of hazards. Not in the form of sharks, hurricanes, or flooding; but a subtler contender – algae.
Flanked by the Gulf of Mexico on the west, the Atlantic Ocean to the east, and the limestone aquifer underground, Florida’s ecosystem is entirely connected to its water shed. Algae growth has always been a natural and primarily healthy organism within the aquatic ecosystem; so when does algae growth become a problem?
In the recent years, the terms ‘Red Tide’ and HAB (Hazardous Algae Blooms) have become common terminology for Florida natives and tourists. Red tide is generally associated with the Gulf of Mexico and HAB Bluegreen algae blooms are associated with Okeechobee river near south-eastern Florida.
‘Red Tide’ is associated with the organism, Karenia brevis, a microscopic algae that occurs normally in low concentrations. In algae blooms, the concentration becomes so high that the water takes on a different color, hence the term ‘red-tide’. The algae blooms produce excessive levels of toxin which can paralyze and kill fish. This toxin can then accumulate in other fish and shellfish, which when eaten by humans, can produce serious illness or death.
HAB Bluegreen algae blooms are associated with cyanobacteria. These algae blooms produce neurotoxins which can cause nerve and brain damage. HAB’s occurrence has risen over the past years as our water shed direction changed in the ‘Treasure coastline’ of south-eastern Florida. This guacamole color sludge is a man-made affliction from human waste and fertilizer run off into Lake Okeechobee – a diagram can be seen here. Under normal circumstances, the water run-off heads into the everglades. With new land development near the everglades, water run-off is now being diverted. The Army Corps of Engineers will pump and divert the freshwater runoff from Lake Okeechobee’s outlying developments and sugar cane fields, towards the intercoastal, where it accumulates and grows HABs.
In June of 2016, governor Rick Scott declared a state of emergency in response to massive HAB’s forming off the southeastern coastline. Through sea-level rise and global warming, there has never been a more dire time to protect Florida’s watershed and coastlines.

So you or your spouse are pregnant. Naturally you want the best possible outcome for your newborn. You may want to reconsider consumption of certain fish and shellfish during pregnancy. A recent study conducted by the National Institute of Health(NIH) has revealed “Adults with high prenatal exposure to methylmercury, which mainly comes from maternal consumption of fish with high mercury levels, did not experience the faster cognitive processing and better short term memory benefits of exercise that were seen in those with low prenatal methylmercury exposures”.

U.S. Marshals Service seized more than 4 million pounds of product
produced by Valley Milk Products LLC (Valley Milk) of Strasburg,
Virginia. The seized products include dry nonfat milk powder and
buttermilk powder packaged in 40- and 50-pound bags for further
manufacturing and are worth nearly $4 million.
Department of Justice filed the complaint, on behalf of the FDA,
alleging that the seized products are adulterated under the Federal
Food, Drug, and Cosmetic Act.
an FDA inspection of Valley Milk, FDA investigators observed poor
sanitary practices and reviewed the company’s records, which showed
positive results for Salmonella in the plant’s internal environmental
and finished product samples. In addition, swabs collected during the
inspection confirmed Salmonella on surfaces food came into contact with
after being pasteurized.
"The FDA urged Valley Milk to conduct a voluntary recall of the
implicated products," said Melinda K. Plaisier, the FDA’s associate
commissioner for regulatory affairs. "The firm refused to recall and, as
a result, we have had to intervene and seize this adulterated food to
prevent it from reaching consumers who could be exposed to Salmonella
from these products." More information here: http://go.usa.gov/x8URq
Miami, FL is now home to the state's first legal needle exchange program!
"At the IDEA exchange, the containers offer two choices for
participants. Inside one, they can trade out needles, as well as pick up
related items — cotton balls, tourniquets, cookers and sterile water —
for injecting the drugs safely. Staffers have bandages and antibiotic
ointments on hand, too, to care for the infections and abscesses dirty
needles can cause.
In the other trailer, participants can get
linked to substance abuse counseling and medical care at a UM clinic
two blocks away, or be tested for diseases like hepatitis C and HIV. The
clinic is the only place in the county where the test results are not
logged for research purposes.
Weeks from now, another box will hold Naloxone, the drug that saves
narcotics users from their overdoses. Soon, the clinic will give away
the life-saving drug as part of its overdose prevention outreach."
