Methylene Glycol in hair straighteners
Methylene glycol is an ingredient
used in some hair-straightening
products. It is formed by the reaction
of formaldehyde with water.
Formaldehyde is a toxic substance,
and since the reaction with water
is reversible, products containing
methylene glycol can, under some
circumstances, release formaldehyde.
The question is thus: is the
use of methylene glycol in hair
straightening products safe?

1) Food additives are substances added to foods to preserve flavor, enhance taste and appearance, or improve nutritional value. Common food additives include preservatives, colors, flavors, emulsifiers, and nutrients.
2) Additives are classified as either intentional if deliberately added, or indirect if they enter food unintentionally during processing. Common indirect additives include acrylamide which forms when foods are cooked at high heat.
3) The FDA regulates food additives through the GRAS list and requires a margin of safety be established through animal testing before human use. The benefits of extending shelf life and preventing spoilage are weighed against any potential health risks.
Food labels
Food labels provide important nutritional information but do not tell the full story of how food is produced and what ingredients it contains. Labels typically do not indicate whether a product was produced sustainably or contains genetically modified organisms (GMOs) and other questionable additives. Many common food additives like high fructose corn syrup, artificial dyes, and preservatives have potential negative health effects and impacts on the environment that are not disclosed on labels. Being more aware of deceptive labeling practices and unfamiliar ingredients is important for making sustainable and health-conscious choices.

Chemical contaminants in milk and dairy products .pdf
Chemical contaminants in milk can be categorized as naturally occurring, intentionally added, or unintentional. Naturally occurring contaminants include mycotoxins produced by molds like aflatoxins, and biogenic amines formed by microbial activity. Intentionally added chemicals are direct food additives and indirect materials from packaging or processing. Unintentional contaminants may arise from agricultural chemicals, antibiotics, toxic elements, or radionuclides. The document discusses specific contaminants like aflatoxins, biogenic amines, pesticide residues, heavy metals, and preservatives. It outlines their sources and potential health impacts to control chemical hazards in milk.
Milk Quality and Residues RELIM Hemling_edited_111115
This document discusses milk quality and residue risks from detergents and sanitizers used in dairy production. It notes that while antibiotic residues have been heavily regulated, detergent and sanitizer residues are an increasing issue as milk trades internationally. Some importers now require zero tolerances for residues, below levels considered safe in the country of origin. This reduces the tools available to maintain animal health and milk quality. The document then reviews major categories that can cause residues, including post-milking teat disinfectants. Sustainable options are needed that are naturally present in milk, such as iodine, hydrogen peroxide, and lactic acid, rather than synthetic chemicals which may form carcinogens or not degrade.
Chemical carcinogenesis and food aduteration
This document discusses chemical carcinogenesis and carcinogens that can be found in everyday life. It begins by defining chemical carcinogens and listing common classes of carcinogens such as epoxides, organohalogen compounds, hydrazines, and aromatic hydrocarbons. It then discusses how carcinogens enter the body and their mechanism of causing cancer through DNA damage and mutations. Examples are given of carcinogens found in microwave popcorn, fruit ripening agents, paneer, plastics like BPA and styrene, and pesticides. Prevention strategies suggested include reducing exposure to these chemicals.
Organic foods beth daws
This document compares organic and conventional foods and their regulatory definitions. Organic food is regulated by the USDA and must be produced without synthetic pesticides, fertilizers, or genetic engineering. While organic farmers can use certain approved substances, any violations of standards will result in loss of organic certification. Conventional foods are not defined by the USDA but may contain substances like nitrites and sulfites that can pose health risks. Overall regulatory oversight of conventional agricultural practices is more limited compared to organic.

PRESENTATION ON CHEMICAL POISONS IN FOOD HYGIENE, SAFETY & SANITATION BY STEP...
Chemical poisons include chemical hazards or chemical food contaminants and cause adverse health effects in humans on ingestion and inhalation.
Chemical food contaminants substances are present naturally in the usual raw material used for food production or added during the regular production process. Failure to handle, store and label cleaning chemicals properly are the most common causes of chemical contamination. If added to food intentionally, quantities should be that are not beyond the acceptable limits established by the Food and Drugs Act and its regulations. To minimize the health risk from natural toxins in food, people are advised to:
-Not assume that if something is 'natural' it is automatically safe.
-Throw away bruised, damaged or discolored food, and in particular moldy foods.
-Throw away any food that does not smell or taste fresh, or has an unusual taste.
-Eat mushrooms or other wild plants that have definitively been identified as nonpoisonous.
Effects of Chemical Hazards on
#Health implications include:
-Harmful chemicals may disrupt body metabolism e.g., mercury can affect developing brains in fetuses, infants and children.
-Can cause cancer.
-Can lead to damage of genes.
-Can alter organ functions.
-Can cause malnutrition in the body that can lead to declination of immunological defenses, impair psycho-social facilities, and cause intrauterine growth retardation.
-Can cause increased rate of gastrointestinal diseases.
-Excessive intake of chemicals in food can cause neural and kidney damage, congenital disabilities and reproductive problems.
#Hospitality establishment implications:
-Leads to poor image and reputation.
-Can cause legislative actions after sues by customers.
-Workers can be exposed to many dangerous levels for many years with no obvious illness.
-Can cause shutdown of the hospitality establishment.
-Leads to loss of jobs of various personnel as affirmative actions are taken by the establishment.
#Hygiene and Food Legislation
These are laws designed to protect consumers from contaminated and dangerous foods, which can lead to ill-health conditions, and also from false information about certain foods.
#Importance of Food Legislation
-To protect the health of the consumer.
-To protect the consumer from fraud.
-To ensure the essential quality and wholesomeness of foods.
For this reason, it is necessary to ensure that the sources of food production are inspected and, quality control and standardization are observed.

- 4. How is preservatives related to embalming? A preservative is a naturally occurring or synthetically produced substance that is added to products such as food, pharmaceutical, human remains etc. to prevent decomposition by microbial growth or by undesirable chemical changes. 3 goals of embalming are thus sanitation, presentation, and preservation.
- 5. Preservative and Class It is also good commercial practice to avoid preservatives where possible as "chemicals" in food may be avoided by consumers. It is also good commercial practice to avoid preservatives where possible as "chemicals" in food may be avoided by consumers. Different preservatives are effective against different reactions. It requires some chemistry and usually some practical experience with a given product to identify which reactions are likely to be a problem.
- 6. Why Preservative are so Interesting! Everyone can cook food, presentation attests to the artistic nature of the experience to set it apart from an everyday experience. Salt not only makes food taste good but also help to make foods--look good. The artistry is not merely flavor or preservative but, in how it appeals to the eye. The kind of attention to detail is as important as looking at a deceased member that has preservatives injected in them for a viewing. Since it indicates that you value families enough to go to the trouble to try and achieve something beyond. Preserving a body is part of the gift you're giving the family.
- 7. Do preservatives have a shelf live? Could they expire?
