Chocolate Allergies Linked to Cockroach Parts

Most people who are allergic to chocolate aren't having a reaction to cocoa or any of chocolate's other official ingredients. No, the flare ups are most likely triggered by the ground-up cockroach parts that contaminate every batch.

According to ABC News, the average chocolate bar contains eight insect parts. Anything less than 60 insect pieces per 100 grams of chocolate (two chocolate bars' worth) is deemed safe for consumption by the Food and Drug Administration.

Allergists say most foods contain natural contaminants. Aside from chocolate, cockroach parts also make their way into peanut butter, macaroni, fruit, cheese, popcorn and wheat. The roach bits can affect people with asthma, as well causing migraines, cramps, itching or hives in people who are allergic to them.

The first cockroach allergy was reported in 1943, and skin testing for cockroaches began in 1959. Cockroach allergies can be treated with allergy shots that contain trace amounts of the insect. [Could Edible Bugs Solve World Hunger?]

According to Morton Teich, an allergist at Mount Sinai School of Medicine, contamination by cockroaches and their droppings is unavoidable, because it happens at cocoa beans' source — the farms where they are produced. Preventing them from infiltrating the harvest would require the use of more pesticides, which Teich says are much worse for you than consuming a few extra bug parts.

Avoiding insects in your food is "almost impossible," Teich told ABC. "You probably would have to stop eating completely."

Comcast Cable Box Comes With Cockroach Surprise - As Company is Sued For Very 'Buggy' Gear

Comcast is under fire in Illinois for installing buggy hardware -- literally. An Illinois resident says the company installed a set top box that came with a free cockroach infestation, and once installed resulted in the bugs "pouring out" into his home. When the user went to complain about the used device and his new friends, Comcast took several days to address the problem, the user going so far as to bring a bag of dead roaches into the Comcast office. While normally you'd think this was an isolated incident, Chicago's being sued by nearly a dozen current and former employees who say they were forced to install the "buggy" gear:

The employees claim they would find cockroaches crawling in and out of equipment, and in their lockers, trucks and equipment bags. They also claim the South Side facility had rats, a leaky ceiling and birds that flew in and out of the warehouse. The employees claim they saw cockroach eggs fall out of cable boxes that were supposed to be installed in customers’ homes. When an employee complained, the supervisor said, “just put the box in — you’re in Englewood. They’ll only have cable for a month. They won’t pay bills,” the suit said.

While Comcast was busily installing bug-infested equipment in low-income Illinois homes, the company was making great political hay from a low-income broadband offer most users can't get. "Comcast adamantly denies the allegations and will vigorously defend itself in court," a Comcast spokesman insists.

Biofuel Cells May Turn Cockroaches into Cyborgs

The sugars in a cockroach's belly have been harnessed by a fuel cell and converted into electricity, a big step toward turning insects into cyborgs, scientists are reporting.

Once miniaturized to the point that the fuel cells are non-invasive to the cockroaches, they can be implanted to power sensors or recording devices, for example.

A rechargeable battery inserted along with the so-called biofuel cell would store the trickle of energy it generates, explained Daniel Scherson, a chemist at Case Western Reserve University in Cleveland.

"If you want to be futuristic, one may use the energy stored to try to control the neurological system of the cockroach and then you might be able to (control) the cockroach (with) a joystick," he told me.

Yes, in the future, that nasty cockroach scurrying across the kitchen floor might actually be a spy set loose by a nosy neighbor, or the CIA.

Sugar Fuel

The power supply for this fuel cell is food the cockroaches eat, avoiding the need for devices that harness electricity from movement, such as shoes that turn mechanical energy into electricity.

The fuel cell devised by Scherson's team uses a cascade of reactions by enzymes to convert energy stored as sugars into electricity.

The first enzyme breaks down the sugar trehalose, which cockroaches constantly produce from their food, into two simpler sugars.

A second enzyme oxidizes the simple sugars, releasing electrons that "can then be funneled together to electrodes where they are captured and delivered to oxygen," Scherson explained.

The team first tested the system on trehalose solutions, then inserted prototype electrodes into the belly of a female cockroach. It worked.

The biofuel cell produced a trickle of electricity — 0.2 volts. Full details on the system are published online in the Journal of the American Chemical Society.

Intermittent Tasks

Since the researchers don't want to load down a bug with a heavy fuel cell and impair its ability to move, they envision storing the energy up in a battery, then using that energy to perform tasks such as power sensors.

One potential application is to equip social insects such as bees or ants with sensors tuned to detect a dangerous chemical and send them out to the environment.

Periodically, the sensor would turn on and broadcast its finding, shutting down between broadcasts to allow the battery time to recharge.

Operating at 0.2 volts is enough power to send a message a few inches, according to Scherson, far enough that a message could be sent down a line of ants spying on a top-secret meeting in a park.

To get there, the researchers need to shrink their fuel cells so they can be fully implanted, find long-lasting materials to make them with so they don't breakdown inside the bugs' bodies, and build the signal transmitters.

All of this is in the realm of possibility, noted Scherson.

"People do wonderful things with circuitry."

Cockroaches, Bed Bugs, Mold Spark $10M Lawsuit

A civil lawsuit alleging long-term substandard living conditions against the owner of the Cordova Estates apartments in Rancho Cordova is seeking $10 million in damages for 97 tenants.

"It's horrific. It's disgusting. I can't describe it. I was without heat for three years," said tenant Jessica Munoz, the named plaintiff in the lawsuit.

The lawsuit, filed this month, alleges that the property owner, Juvenal Campos, did not fulfill his duty to maintain habitable apartments for tenants paying $525 to $725 per month in rent.

A prepared statement sent by "the owners" of the property stated that they are trying to address issues in those apartments.

"We are disappointed by the filing of this lawsuit," read the statement which was signed "the owners".

Meanwhile, Rancho Cordova code inspectors stress Campos is facing a string of code violations based on a recent walk-through of the apartment complex.

"He is facing roughly 150 violations ... He could face fines in the hundreds of thousands of dollars if we continue to come out and things not be done," said Kerri Simpson, Rancho Cordova Code Enforcement officer.

City officials said they are working the property owner to fix the owner. However, Simpson said previous agreements to fix problems in the past failed.

Being in the pest control trenches you get to see some pretty cool stuff!!! OK, it’s cool to us pest control people but to “normal” people it’s utterly disgusting! What you see it a juvenile (nymph) American Cockroach molting out of its exoskeleton to go to its next growth stage. They go through 6-14 growth stages from egg to adult. Newly molted roaches are white in color but quickly turn to their normal color (reddish-brown) within a hour or so. To many people these things are called the “water bug” or “palmetto bug.”

(click images to enlarge)

They are common in commercial buildings as they often enter structures from city steam and sewer pipes. EHS are experts when it comes to cockroach elimination.

AirTran Sued Over Cockroaches on Flight

You've heard of snakes on a plane, now here come bugs on a plane.

A North Carolina couple is suing AirTran Airways, alleging that cockroaches crawled out of air vents and overhead carry-on bins during a flight from Charlotte to Houston in September.

Attorney Harry Marsh and his fiancé Kaitlin Rush say the insects appeared soon after takeoff, and when Marsh pointed them out to flight attendants, they did nothing to help.

"These roaches and other pests caused great distress to a number of passengers throughout the flight," the complaint states.

All paying guests of the airline are entitled to "clean, pest-free" accommodations, it goes to to say.

The couple accuses AirTran of negligence and recklessness, infliction of emotional distress, nuisance, false imprisonment and unfair and deceptive trade practices, and is suing for more than $100,000 plus the price of their tickets.

In a response to the complaint filed with the U.S. District Court for the Western District of North Carolina, AirTran denies most of the allegations.

CNN legal analyst Sunny Hostin predicted the case would never go to trial.

"This is a case that's going to settle. Bottom line, I foresee a lot of free flights for this couple if they want to get back on AirTran," Hostin said.

"It's certainly not a pretty picture. The roaches were out long enough for them to take video and photographs, so that's exhibit A."

Plague of Cockroaches Leaves Scientists Baffled

Cockroaches have returned to Moscow while experts were guessing why – and where – the unwanted guests had apparently disappeared.

Residents of Mal. Gruzinskaya Ulitsa were the first to witness thousands of cockroaches that suddenly appeared in the central area.

“The floor is just covered with them, we’ve got tired of sweeping it!” local flat owner Larisa told Vesti-Moskva TV-channel. “Most of them are on windowsills, look – those guys are just hanging out!”

Mystery invasion

The reasons for the cockroach invasion are unclear, and experts say they did expect to see them again after a sudden disappearance but didn’t think it was going to happen overnight.

Professor Dmitry Mukha, the head of the laboratory for biological diversity, thought cockroaches would get used to the latest pesticides in five years time, he told Komsomolskaya Pravda just before the invasion.

“When they develop tolerance to these chemicals, a second wave will appear then,” he said, adding that his laboratory is currently working on the new remedy.

However, cockroaches decided to come back before the arrival of a new pesticide that would help humans win the war “for a long time, if not forever”, as the professor hoped.

Endangered cockroaches?

The sudden plague comes after a sharp drop in cockroach numbers, which had led some biologists to propose adding the pests to the list of endangered species.

“Although they are parasites, every species bears a unique gene pool,” Alexandr Logunov, acclaimed ecologist and one of the creators of Russia’s Red Book, told KP.

His “natural modesty” and “people’s dislike” of the most widespread German cockroaches didn’t let him nominate this breed for the list, he said, but soon he was going to do so.

As an endangered species, cockroaches would be protected from angry residents – but for now at least there is no restriction on how to control them.

Hardy Germans

However, there seems to have been some ethnic cleansing going on among the cockroach ranks.

Only German cockroaches, who were first brought here by Russian soldiers returning to the motherland after the war with Prussia in the middle of the 18th century, have came back now.

And their oriental brothers – who appeared long before during the Mongol invasion – are still very rare – and not only due to some unknown Chinese pesticide that was widely sold in the end of the 90s.

Mukha believes that the superefficient chemical has nearly eradicated all breeds of cockroaches in Moscow, and Loginov added that the Oriental cockroaches are more vulnerable in general.

Unlike German cockroaches, female oriental cockroaches don’t carry their eggs on them, the biologist said.

“And of course, in premises where both breeds lived, German cockroaches would certainly eat any eggs they found from their neighbors,” he explained.

Cockroach dookie? OK, it is not the most technical term but it sure does get the point across! We all know that having roaches where we eat & live is socially unacceptable but...

Exactly how unhealthy is it? This video is graphic proof that the bacterial levels associated with cockroaches is extremely high! Look at the bacteria count after just 24 hours time with a simple swab of “dookie.”

What if this is a commercial food handling facility like a restaurant or food manufacturer? You have an obligation to protect the public in addition to your brand. Even a few cockroaches can cause a serious issue.
