Foray 48b

This is the spray currently being used to spray the Painted Apple Moth and the Asian Gypsy Moth.

With the Auckland Painted Apple Moth Eradication Programme the number of people that need to reduce or eliminate their contact with the Foray 48b spray has been stated as approximately 4 in every thousand. These figures exclude people that did not report their problems. These also exclude where people reporting their ailments were told that their problems were not due to the Foray 48b spray (we have been unable to confirm that their ailments were not due to the spray, we have also had reports that some people have been told that their problem is just in their head).
The planned spray rate for the Hamilton spray programme is 3 times more often and up to 3 times stronger so health effects will be much more pronounced.

Foray 48b is not an organically certified pesticide.

It uses Btk as the active ingredient to deal with these pests and works by being ingested by caterpillar and giving them a stomach ache so they stop eating until they die of starvation days later. The Btk accounts for 2.1% of the spray. Btk is used in several organic sprays.

The remainder 97.9% of the spray is called inert substances - not because they do not react or are neutral but because they do not affect the caterpillar. The exact ingredients that make up this 97.9% of the spray is a trade secret.

Detail

Methyl paraben (methyl hydroxybenzoate)

Effects:

bulletWell known sensitiser causing allergic reactions, especially to skin. Irritating to eyes, skin, respiratory system, gastrointestinal system.
bulletPropylene glycol increases the activity of this chemical.

Where Found:

bulletPreservative. Found in food: mayonnaise, salad dressings, spiced sauces, mustard, processed veggies, frozen dairy products, baked goods, jellies and jams, soft drinks, fruit juices, syrups, sweets.
bulletFood code number = 218.
bulletAlso cosmetics, shampoos, moisturizers, sunscreens, shoe polishes, even textiles.

Propylene glycol

Effects:

bulletIrritation to skin, eyes and mucous membranes.
bulletAggravation of kidney disorders.
bulletSome evidence of liver damage in laboratory tests.
bulletDamage to intestines.
bulletReproductive effects.
bulletEffects on red blood cells: decrease their life span; also other blood effects (increased osmotic pressure).
bulletNodules in spleen.
bulletHas been associated with deafness- Martindale recommends that it is not used in ear drops
bulletDepression of central nervous system, especially in children:
bulletReports of seizures in children taking multivitamin formulations containing propylene glycol;
bulletCNS depression causing mortality has been described in premature infants after repeated exposure to medication containing propylene glycol. CNS effects have also been observed in children dermally exposed to propylene glycol.
bulletA case of propylene glycol intoxication in a premature infant is reported. The infant went into a state of coma after treatment for burns with antiseptic dressings. Cessation of the topical treatment resulted in complete recovery. An exceptionally high level of the dressings' solvent, propylene glycol, found in the urinary chromatogram, was believed to be the causative agent. It is suggested that topical preparations containing propylene glycol should not be used in premature infants- during the first weeks of life.
bulletThe case of a 2-yr-old boy who developed a marked metabolic acidosis and CNS depression as manifestations of serious propylene glycol (PG) poisoning following an accidental ingestion of an estimated 3 ounces of hair gel that contained 1.75-2.25% PG is reported. The child experienced 3 to 5 episodes of spontaneous vomiting shortly after being discovered.
bulletPolyethylene Glycol esters and diesters can enhance the skin penetration, and the effect, of other chemicals, particularly steroids, by interacting with the lipid bilayers.
bulletVery little inhalation data available, but it appears that it may be more toxic by inhalation than oral ingestion.

Where found:

bulletPropylene glycol is used in antifreeze formulations, heat exchangers, and brake and hydraulic fluids. It is also used in the manufacture of resins, as a solvent in pharmaceuticals, cosmetics and inks, as a food additive and plasticizer for resins and paper, and as a humectant in textiles and tobacco.
bulletPropylene glycol is absorbed completely from the gastrointestinal tract and partly via the skin and the lungs.
bulletFood Code number = 1520
bulletMany cosmetics, pharmaceuticals, food preservative.

Benzoic acid/sodium benzoate

Effects:

bulletAnaphylactic reactions.
bulletAsthma, urticaria, rhinitis,
bulletRespiratory sensitivity in aspirin-induced asthma
bulletIrritant to skin and eyes - contact urticaria.
bulletDiarrhoea, muscle weakness, tremors, emaciation, degeneration of the liver.
bulletToxicological data and risk assessment assumes ingestion, but studies indicate that there is no safe level for inhalation of this chemical.

Where Found:

bulletPreservative. Found in food: oils, ice creams, tinned mushrooms, chilli paste, imitation fruit, icings, sports supplementary foods, sauces, dressings, veggie and fruit pulp, preserved cherries.
bulletFood Code number = 210, 211

Where found:

bulletPreservative: ice cream, tinned mushrooms, dried fruit.
bulletFood Code number = 202.

Hydrochloric acid

bulletAcidity regulator. Corrosive.
bulletIrritant. Food Code number = 507.

NOTES:

(1) Sensitiser describes a substance that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemical. This allergic reaction may be to the substance itself, or to another energy source, quite often the sun. (personal communication)
