2013 Technical Committee Meeting Materials – Sanitation

North American Millers’ Association
Background/Briefing Paper


Methyl bromide

Methyl bromide (MB) has been an important tool for controlling insect pests in flour mills and warehouses. MB was to be banned with no exceptions on Jan. 1, 2001. However, NAMA successfully convinced Congress of the importance of MB as a sanitation tool, and Congress amended the law to set a new phase-out date of Jan. 1, 2005. The new law also provided opportunities to apply for “critical use exemptions.”  The milling industry has cut its use of methyl bromide by about 95 percent. Methyl bromide use in mills will cease on Dec. 31, 2014.

Sulfuryl fluoride

Responding to a legal challenge of EPA’s tolerances for sulfuryl fluoride (SF) residues on foods, in 2011 the agency proposed to revoke those tolerances and cancel all associated uses. NAMA submitted 47 pages of detailed comments urging EPA to allow mills to continue using this sanitation tool.

EPA announced a second request for comments on its proposed order in 2012. In response, NAMA submitted another 11 pages of technical comments specific to milling industry usage. NAMA said it believes a thorough analysis and consideration of the comments will lead EPA to conclude a revocation of SF residue tolerances is not warranted, nor would a revocation confer health benefits for the nation’s consumers.

Even EPA states that SF’s contribution to total fluoride in the diet is “tiny.” A coalition of SF user groups including NAMA is aggressively advocating for EPA to provide flexibility to accommodate trivial SF residues on food. The coalition has been working for a year to get enabling language included in the farm bill.
