'Food Deserts' or Mirages?
How many people live there?

by Richard Belzer

in ,

Sometimes an urban "food deserts" is in fact a mirage because of a significant error in the data or a cramped, unrealistic definition of "low access" that disregards nearby stores in adjacent census tracts.

Only 7 census tracts in Washington, DC are identified as "food deserts." In one case, the reason is not a lack of access so much as the government's cramped definition of an acceptable grocery store. In one other case, the reason is the government's definition disregards large grocery stores in adjacent census tracts that lie within one mile of where people actually live. For the remaining five census tracts, no large grocery stores appear to be nearby under any reasonable definition of the term. But these census tracts are predominantly industrial.

'Food Deserts' or Mirages?
A second look at the data

by Richard Belzer

in , ,

Yesterday's post on the federal government's new program to eradicate "food deserts" provided an obvious example in which the database yields nonsensical results. A large US Army installation, one with its own grocery store, no unemployment, and essentially no poverty, nevertheless appeared to meet all of the government's (arbitrary) criteria for inclusion.

A closer look shows that there is yet another reason why this particular "food desert" is a mirage. Soldiers who live within this census tract actually do live within one mile of a second, large grocery store--albeit one that is in an adjacent census tract.

'Food Deserts' or Mirages?
A look at the data

by Richard Belzer

in , , ,

One of the latest trends in federal government food policy is the eradication of "food deserts" -- places where it is said to be difficult to find fresh produce. The Economic Research Service of the US Department of Agriculture has created an interactive map to help you learn whether you live in a "food desert".

The data are interesting, but perhaps not for the intended reason.

Counting Jobs Created or Saved by the "Stimulus" Bill, Part 2:
Program design prevents error correction

by Richard Belzer

in

The federal government's reported figures for jobs "created or saved" by the "stimulus" bill (formally the American Recovery and Reinvestment Act of 2009, or "ARRA") are now known to be wrong. The Recovery Accountability and Transparency Board, which oversees these figures, apparently has decided not to correct them.

Counting Jobs Created or Saved by the "Stimulus" Bill:
A lesson in information quality

by Richard Belzer

in

A scandal has erupted over the federal government's reporting of the number of jobs created or saved by the "stimulus" bill (formally the American Recovery and Reinvestment Act of 2009). 

This scandal would have been avoided if the government had complied with the Information Quality Act.

National Organic Program:
Is it 'going to seed'?

by Richard Belzer

in

Washington Post staff writers Kimberly Kindy and Lyndsey Layton say the US Department of Agriculture's National Organics Program is falling short, allowing synthetic ingredients or to be used in making organic foods.

In their long Page One story, Kindy and Layton never reveal crucial facts about the National Organic Program: it's a marketing program, not a food safety program.

Who Pays the Cost of Regulation?
Insights from corporate income tax incidence

by Richard Belzer

in

Regulation is widely understood as a tax on the activity or person being regulated. Where these activities repair genuine market failures, benefits from regulation may result. If there are benefits from, say, automobile safety regulation, one would expect the beneficiaries to be persons who otherwise would have been killed or injured at the pre-regulatory safety level.

But what about the costs of regulation? Who bears them? More...

"Generic HAACP Plans for Regulatory Analysis"
Do federal HACCP regulations meet HACCP standards?

by Richard Belzer

in

An important element of Monday's post on E. coli and irradiation was the recognition that years of federal regulations had failed to significantly reduce foodborne illness risks. Conducting research for the post brought back memories of having reviewed the Food and Drug Administration's and Food Safety Inspection Service's initial regulations implementing the Hazard Analysis and Critical Control Points (HACCP) inspection regime.

Those reviews led to a presentation and a food safety conference, and the presentation led to a paper that was published as a chapter in a book on the economics of HACCP. (Amazon ranks the book #2,020,211, but hurry: as of Monday night they had one copy left.)

E. coli and Irradiation
Would irradiation have prevented the recent outbreaks?

by Richard Belzer

in ,

Last fall's E. coli O157:H7 outbreak in spinach has now been followed by an outbreak in lettuce used by certain fast food enterprises. Today's Wall Street Journal includes an editorial criticizing "E. Coli's Enablers," by which they mean activists who oppose irradiation.

Would irradiation of produce intended to be consumed raw have prevented these outbreaks?

Pathogens in Fresh Produce:
Is zero risk feasible?

by Richard Belzer

in

Investigators have found the cattle ranch that appears to be the source of the E. coli O157:H7 bug that infected a spinach farm a mile away But they haven't figured out how the bug traveled the mile between the two locations.

Industry and food safety experts alike are encouraging the public to expect fresh produce to have zero microbial risks. Is that feasible?

Source of Spinach Contamination Found:
Cattle ranch a mile away from the spinach fields

by Richard Belzer

in

USA Today reporters Elizabeth Weise and Julie Schmit say the E. coliO157:H7 bug responsible for the recent spinach outbreak has been positively matched to a farm in the Salinas Valley. Although the farm has not been identified, the story provides enough information to suggest that, at a minimum, federal Good Agricultural Practices are too vaguely defined to be useful. Making them mandatory, which Earthbound Farms implies government should have done to prevent the outbreak, is unlikely to help. More...

The Market for Pickers and Packers:
The market for agricultural labor isn't really different

by Richard Belzer

in

Sonya Geis reports in today's Washington Post that there is an acute labor shortage in California's Central Valley. There are not enough workers to harvest and pack the tree fruits that are ready to go to market.

Growers and packers interviewed by Geis blame the shortage on a combination of intensified immigration enforcement, competition for unskilled labor from other industries such as construction, and the complexities of the federal government's H-2A visa program. None apparently have considered the possibility of solving the labor shortage by raising wages.

Federal "Good Agriculture Practice" Guidance:
What does the guidance say about the use of manure?

It is said that federal "Good Agricultural Practice" guidance ensures that fresh produce does not transmit pathogenic foodborne illness. Is this a reasonable inference? More...

Agency Responses to NAS Questions on Risk Assessment Practice

by Richard Belzer

in ,

In June, the ad hoc National Academy of Sciences committee empaneled to review OMB's proposed risk assessment guidance asked several affected federal agencies to provide comments.
