FAT TOM
F.A.T.T.O.M. explains what allows foodborne pathogens to grow. You'll also learn some important food safety terms.
FAT TOM will help you to remember these valuable terms:
Food
Acidity
Time
Temperature
Oxygen
Moisture
Food Safety information for consumers, educators, and those working in the food service industry. The information is based on recommendations found in Food Code 2009. Food Code 2009 represents the most recent science-based information about good food safety practices.
Food: There are sufficient nutrients available that promote the growth of microorganisms. Protein-rich foods, such as meat, milk, eggs and fish are most susceptible.
Acidity: Foodborne pathogens require a slightly acidic pH level of 4.6-7.5, while they thrive in conditions with a pH of 6.6-7.5. The United States Food and Drug Administration's (FDA) regulations for acid/acidified foods require that the food be brought to pH 4.5 or below.
Time : Food should be removed from "the danger zone"
within two-four hours, either by cooling or heating. While most guidelines state two hours, a few indicate four hours is still safe.
Temperature: Food-borne pathogens grow best in temperatures between 41 to 140 °F (5 to 60 °C), a range referred to as the temperature danger zone (TDZ). They thrive in temperatures that are between 70 to 104 °F (21 to 40 °C).
Oxygen: Almost all foodborne pathogens are aerobic, that is requiring oxygen to grow. Some pathogens, such as Clostridium botulinum, the source of botulism, are anaerobic.
Moisture: Water is essential for the growth of foodborne pathogens, water activity (aw) is a measure of the water available for use and is measured on a scale of 0 to 1.0. Foodborne pathogens grow best in foods that have aw between 0.95 and 1.0. FDA regulations for canned foods require aw of 0.85 or below.

Herbicide (Make UP)
Herbicide, likewise normally known as weedkillers, are compound substances used to control undesirable plants.Selective herbicides control particular weed species. Non-specific herbicides can be utilized to clear waste ground, mechanical and development locales, railroads and railroad banks as they execute all plant material with which they come into contact. Other essential refinements persistence (How long the item stays set up and stays dynamic), method for uptake (whether it is consumed by over the ground foliage just), and mechanism of action (how it works).
Salt and other metal salts were utilized as herbicides, however these have step by step dropped out of support and in a few nations some of these are banned because of their industriousness in soil, and lethality and groundwater sullying concerns.
More research is expected to know the short-and long term impacts of pesticides on people. Albeit a few studies have discovered associations between some childhood cancers and a pesticides, different studies have not achieved the same conclusions. Numerous pesticides disturb the sensory system of bugs, and research has demonstrated that they can possibly harm the neurological system of youngsters.
This is particularly ture for herbicides to harm other lives, since they are dangerous to a wide assortment of plant species, and not only the weeds. In this way, the broadcast spraying of herbicides results in broad exposures non-target species, which can bring about a unintended yet generous mortality of non-target plants. Just these aggressive plants are weeds, and these are the main focus of a herbicide application.
However, there are numerous other, non-bug types of plants in the field or manor that don't meddle with the development of the product plants, and these are additionally influenced by the herbicide, however not to any advantage regarding vegetation administration. Truth be told, particularly in ranger service, the non-target plants might be advantageous, by giving sustenance and natural surroundings to creatures, and averting disintegration and draining of supplements.

how to find the how tobuild the new sewage treatment system for the homeowners
The city of San Diego water system http://thewatchers.adorraeli.com/2011/09/09/san-diego-power-outage-caused-2-million-gallons-of-raw-sewage-spilled-into-los-penasquitos-lagoon-and-sweetwater-river/
Sewage treatment system in china
The propose of this blog is to show how to find the how to build the new sewage treatment system for the homeowners.
People could find the 6 steps for how to build the new
sewage treatment system for the homeowners on the official website of the Ohio
department of health. First of all choose the S from the A-Z Index, and then
find the link to the sewage. Under the webpage of the sewage, choose homeowner
and click the Steps for Constructing a New Sewage Treatment System.
This link will guide people to build a new sewage treatment
system.
The first step is to contact neighborhood health district
for particular data on STS permitting. We also need the information about when
starting to build the land advancement with a STS. Neighborhood health district
will visit your site to start the process.
The second step is Obtain a site and soil assessment. A complete
assessment of the dirt on the property is expected to decide how much usable
soil is available and where it is found. Other site conditions should likewise
be resolved, for example, slant, geology and the area of close-by water sources
and drinking water supplies.
The third step is to work with a sewage treatment system
plan to assess the different types for your parcel. Householders ought to
painstakingly assess all kinds of costs including establishment, long operation
cost and maintenance and administration contract costs before settling on a
final choice.
The fourth step of the plan is to obtain quotes and bids
from registered STS contractors.
Step 5: The neighborhood health district will perform a last examination of your
system or object the establishment.
Step 6: Proper operation and support of your new STS is
vital to guarantee the system works. Contingent upon the multifaceted nature of
your system, an administration contract might be required.

Water quality coliform bacteria
Water quality coliform bacteria
Coliform bacteria are a commonly used bacterial indicator
of sanitary quality of foods and water. They are defined as rod-shaped
Gram-negative non-spore forming and motile or non-motile bacteria which can
ferment lactose with the production of acid and gas when incubated at 35–37°C.
While coliforms themselves are not normally causes
of serious illness, they are easy to culture, and their presence is used to
indicate that other pathogenic organisms of fecal origin may be present. Such
pathogens include disease-causing bacteria, viruses, or protozoa and many
multicellular parasites. Coliform procedures are performed in aerobic or
anaerobic conditions.
Water pollution caused by fecal contamination is a
serious problem due to the potential for contracting diseases from pathogens
(diseasecausing organisms). Frequently, concentrations of pathogens from fecal
contamination are small, and the number of different possible pathogens is
large. As a result, it is not practical to test for pathogens in every water
sample collected. Instead, the presence of pathogens is determined with
indirect evidence by testing for an "indicator" organism such as
coliform bacteria. Coliforms come from the same sources as pathogenic
organisms. Coliforms are relatively easy to identify, are usually present in
larger numbers than more dangerous pathogens, and respond to the environment,
wastewater treatment, and water treatment similarly to many pathogens. As a
result, testing for coliform bacteria can be a reasonable indication of whether
other pathogenic bacteria are present.
Most coliform bacteria do not cause disease.
However, some rare strains of E. coli, particularly the strain 0157:H7, can
cause serious illness. Recent outbreaks of disease caused by E. coli 0157:H7
have generated much public concern about this organism. E. coli 0157:H7 has
been found in cattle, chickens, pigs, and sheep. Most of the reported human
cases have been due to eating under cooked hamburger. Cases of E. coli 0157:H7
caused by contaminated drinking water supplies are rare.

The air quality index
The air quality index
The air quality index (AQI) of a area means that how
polluted or clean the air in a particular range is. It is measured to keep the
negative health impacts when people come into the area with uncleaned air. The
purposes of this blog are to introduce the air quality index (AQI) and compares
the AQI in Cincinnati area and Cleveland area in Ohio, and show how air
pollution might be controlled.
The air quality index is used to provide the public with an
indication of the air quality in a local area on a daily basis. If focuses on
health effects you may experience within a few hours or days after breathing
polluted air.
We can find the data we need in the home page of the Ohioenvironment protection agency.
According to the application under the Ohio environmentprotection agency, both area in Cincinnati district and Cleveland have good air
quality. Moreover, this does not imply that individuals in the district ought
not take measures to control air pollution. With the guide of the government
and the exertion of people's concerns, air pollution might be in a good
control.
There are few suggestions for the control of the air
pollution, Puja Mondal believed that there are 5 ways to protect the air
environment health. Some of the effective methods to Control Air Pollution are
as follows:
(a) Source Correction Methods: Industries make a major
contribution towards causing air pollution. Formation of pollutants can be
prevented and their emission can be minimised at the source itself.
(b) Pollution Control equipment: it becomes necessary to
install pollution control equipment to remove the gaseous pollutants from the
main gas stream.
(c) Diffusion of pollutant in air: Dilution of the
contaminants in the atmosphere is another approach to the control of air
pollution.
(d) Vegetation: Plants contribute towards controlling
air-pollution by utilizing carbon dioxide and releasing oxygen in the process
of photosynthesis.
(e) Zoning: Zoning advocates setting aside of separate areas
for industries so that they are far removed from the residential areas.

nuclear power plant

Nuclear Power Plant
The purpose of this blogger is to explain what are the
potential health effects from exposure to nuclear power plant leaks into the
environment for Human, Animals, and Plants.
For humans, Kathryn Higley, director of the Oregon State
University department of nuclear engineering and radiation health physics,
expresses that As radioactive material decays, or separates, the vitality
discharged into the environment has two methods for hurting human. It can
straightforwardly kill cells, or it can make changes DNA. On the off chance
that those transformations are not repaired, the cell might turn cancerous.
Radioactive iodine tends to be absorbed by the thyroid gland
and can cause thyroid cancer, said Dr. Lydia Zablotska, an assistant professor
in the department of epidemiology and biostatistics at the University of
California, San Francisco.
Children are most at risk for thyroid cancer, since their
thyroid glands are 10 times smaller than those of adults. For Children, there
are many ways they can get the radioactive effective. For example, Children
were exposed to radioactive material mainly from eating contaminated leafy
vegetables and dairy. There have been no detectable health effects from
exposure to radioactive cesium after the accident.
Animals are particularly susceptible to radiation exposure.
New studies around the Chornobyl reactor accident site have found reduced
numbers of certain species and impacts to genetics.
Specialists looked at monkeys from two districts of Japan,
one gathering of monkeys from the Shimokita locale, 400 Km north of Fukushima
and monkeys from polluted area in Fukushima.
"Fukushima monkeys had significantly low white and red
blood cell counts, hemoglobin, and hematocrit, and the white blood cell count
in immature monkeys showed a significant negative correlation with muscle
cesium concentration. These results suggest that the exposure to some form of
radioactive material contributed to hematological changes in Fukushima
monkeys."

Zika virus, as a member of the virus family Flaviviridae and
the genus Flavivirus, transmitted by daytime-active Aedes mosquitoes. Its name
comes from the Zika Forest of Uganda, where the virus was first isolated in
1947.
According to the U.S. Centers for
Disease Control and Prevention (CDC), Zika virus is related to dengue, yellow
fever, Japanese encephalitis, and West Nile viruses.The infection, known as
Zika fever, often causes no or only mild symptoms, similar to a mild form of
dengue fever. In January 2016, the CDC issued travel guidance on affected
countries, including the use of enhanced precautions, and guidelines for
pregnant women including considering postponing travel.
In February 2016, some researcher believed that there is
evidence to support that Zika fever in pregnant women can cause abnormal brain
development in their fetuses by mother-to-child transmission, which may result
in miscarriage or microcephaly.
However, recently a group of Argentine physicians challenged
the connection between the Zika virus with the miscarriage. The group believed
that the Zika virus is not to blame for the rise in microcephaly cases, but
that a toxic larvicide introduced into Brazil's water supplies may be the real reason
behind it.
According to the Physicians in Crop-Sprayed Towns (PCST), in
2014, a chemical larvicide that produces malformations in mosquitoes was
injected into Brazil's water supplies in order to stop the development of
mosquito larvae in drinking water tanks.
The group of Argentine doctors stated that during past Zika epidemics,
there have not been any cases of microcephaly linked with the virus.
In fact, about 75 percent of the population in countries
where Zika broke out had been infected by the mosquito-borne virus. For
example, Colombia, where there are plenty of Zika cases, are no records of
microcephaly linked to Zika.
The Colombian president said that many of the country's
citizens were infected with Zika but that there was not a single case of
microcephaly. The record shows that 3,177 pregnant women in the country were
infected with Zika, but these women all will have or already had healthy
babies.
