Does methyl bromide leave a residue?
Under normal circumstances gaseous methyl bromide does not present a residue problem. However, there is usually a small, variable amount of permanent residue resulting from the chemical reaction between this fumigant and some constituents of the material.
Is methyl bromide safe for food?
Methyl bromide is also used to treat commodities such as grapes, asparagus, logs, and other imported goods to prevent introducing pests to the United States. Treatments often fulfill official quarantine requirements for international shipments. Methyl bromide is a toxic substance.
What does methyl bromide do to humans?
Methyl bromide is highly toxic. Studies in humans indicate that the lung may be severely injured by the acute (short-term) inhalation of methyl bromide.

How long does methyl bromide last?
Tissue half-lives of methyl bromide range from 0.5 to 8 h.
How long does methyl bromide last in the environment?
Environmental Health Effects Gas-phase methyl bromide will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is about one year.
Is methyl bromide still used on strawberries?
The powerful fumigant methyl bromide will be retired from California’s strawberry fields at the end of this year after more than 20 years of fierce debate over its effects and alternatives.
Is methyl bromide still used in agriculture?
“The use of methyl bromide in California agriculture has dropped significantly over the years as the fumigant is being phased out,” said Charlotte Fadipe, spokeswoman for the California Department of Pesticide Regulation.
Is methyl bromide a carcinogen?
* Methyl Bromide can affect you when breathed in and may be absorbed through the skin. * Because this is a MUTAGEN, handle it as a possible carcinogen–WITH EXTREME CAUTION. * Contact can severely irritate and burn the skin and eyes with possible eye damage, and may cause skin blisters.
What products contain methyl bromide?
Methyl bromide gas is pumped into food storage units to kill a certain mite found on grapes imported from Chile. It is also used in the food processing of rice, pet food, walnuts, plums, figs, raisin, dates and dried pork products to keep pest infestations down, according to EPA documents.
What do farmers spray their strawberries with?
Strawberry growers in California have long depended on methyl bromide, the most effective chemical to control soil-borne pathogens and weeds. Its widespread use has helped make strawberries one of California’s most lucrative crops.
What do they spray strawberries with?
Strawberries are irresistible to pests, especially soil-borne pathogens. Most pesticide comes before the crop is even planted in the form of soil fumigants. The two most common are 1,3-Dichloropropene (1,3-D) and chloropicrin, both of which are banned in the EU.
How can I detect methyl bromide residues in food products?
A simple and rapid method has been developed for fast selective determination of residues of methyl bromide in food products. The method is based on the use of a GC/MS computer-aided system equipped with a headspace.
What is methyl bromide?
Methyl bromide is an odorless, colorless gas used to control a wide variety of pests in agriculture and shipping, including fungi, weeds, insects, nematodes (or roundworms), and rodents.
Why is methyl bromide banned in the US?
Methyl Bromide. Methyl bromide is a fumigant used to control pests in agriculture and shipping. Methyl bromide also depletes the ozone layer. Therefore, along with other countries, the United States has phased out production and consumption of methyl bromide with important exceptions for critical uses as well as quarantine and preshipment.
Do I need to report my methyl bromide sales to EPA?
Most transactions involving methyl bromide (e.g., production, transfer, sale) must be reported to EPA. If you are not sure if you need to report to EPA, please contact us. Methyl bromide reporting forms are due 45 days after the end of the quarterly reporting period.
