Yet another food worry? Nanoparticles.

As You Sow, an advocacy group for environmental corporate accountability, has been paying close attention to nanotechnology.  It has just issued a report, Slipping Through the Cracks: An Issue Brief on Nanomaterials in Foods.

An Issue Brief on Nanomaterials in Foods

 

According to an account in the New York Times, the CEO of As You Sow, Andy Behar, says:

We’re not taking a no nano position…We’re saying just show it’s safe before you put these things into food or food packaging.
Nanotechnology, as I have discussed previously, is the use of tiny particles for many purposes, among them food.  These particles are really, really small, on the scale of nanometers (nm), one billionth, or 10−9, of a meter.
Are they safe to eat?

The FDA’s nanotechnology web page provides a 2007 report from a task force, a 2012 fact sheet, and a draft-for-comment on how industry should deal with nanoparticles in foods and food packaging.

The fact sheet says:

FDA has long encountered the combination of promise, risk, and uncertainty that accompanies emerging technologies…The very changes in biological, chemical and other properties that can make nanotechnology applications so exciting also may merit examination to determine any effects on product safety, effectiveness, or other attributes. Understanding nanotechnol­ogy remains a top FDA priority. FDA is monitoring the evolving science and has a robust research agenda to help assess the safety and effectiveness of products using nanotechnology.

My translation: the FDA has no idea whether this technology is safe or not and is depending on industry to find out.

Because the FDA does not require labeling of nanomaterials (the European Union does), you have to decide for yourself whether this is something you want to add to your list of food worries.

Just a thought: real foods don’t have added nanoparticles.

International food politics: Carving up the UK’s Food Standards Agency

FoodProductionDaily.com has done an analysis of who does what under the new UK scheme for dividing food responsibilities and taking power away from the pesky Food Standards Agency, which had the nerve to actually try to regulate the food industry.

At a time when it is increasingly obvious that food regulations would be better served if under the authority of a single food agency, the UK is doing just the opposite.

Here in America, we have enough problems with food regulations divided between FDA and USDA.  The UK has done us one better.    It now has three agencies in charge.  See if you can make sense of any of these new responsibilities:

The Food Standards Agency

  • Scientific advice on the food safety aspects of date marking
  • Assessment and labeling of ingredients/foods with food safety implications (e.g. allergens, glycols, high caffeine, high glycyrrhizinic acid)
  • Food safety aspects of organic food and of foods controlled by compositional standards
  • Treatments and conditions of use with food safety implications (e.g. quick frozen foods, raw drinking milk and pasteurization, food contact materials)
  • GM and novel foods (including use of nanotechnology)
  • EU General Food Law regulation, including traceability of food
  • Codex Committees on Food Hygiene, Methods of Analysis and Sampling, Food Additives, Contaminants in Foods

Department for Environment, Food and Rural Affairs (a mix of our FDA, USDA, and EPA)

  • General lead on food labeling legislation and relevant EU negotiations
  • Lead on the EU Food Information proposal
  • Country of origin labeling
  • Food composition standards and labeling such as fruit juice and fruit nectars, jams and bottled water
  • Technical advice on compositional standards for food without specific legislation, such as soft drinks and cereal products
  • Fish labeling
  • Use of marketing terms e.g. natural, fresh, clear labeling, vegan and vegetarian labeling
  • Food authenticity program
  • Codex Committees for: Food Labeling, Processed Fruits and Vegetables, Fresh Fruits and Vegetables, Fats and Oils, Fish and Fishery Products, Europe, General Principles
  • Lead on Codex Alimentarius Commission, General Principles and Coordinating Committee for Europe

Department of Health

  • Nutrition related aspects of the EU food information regulation
  • Front of pack labeling
  • Food for particular nutritional uses (PARNUTS)
  • Infant formula and follow on formula
  • Health and nutrition claims
  • Food supplements
  • Calorie information in catering establishments
  • Codex Committee on Nutrition and Foods for Special Dietary Uses

This sounds to me like an ironclad guarantee that nothing will ever get accomplished.  But that, of course, was very point of taking so many responsibilities away from the Food Standards Agency.  That agency, alas, was actually trying to regulate the food industry, something no conservative government is willing to tolerate.

Let’s hope our FDA pays no attention.

GAO on FDA and USDA: irradiation, food safety, and humane treatment of animals

It’s the weekend and I’m cleaning out my e-files.  The Government Accountability Office (GAO), the congressional watchdog agency, has just released a bunch of reports complaining about the way the FDA and USDA do business:

Food Irradiation: FDA Could Improve Its Documentation and Communication of Key Decisions on Food Irradiation Petitions (GAO-10-309R, February 16, 2010, 23 pages).

labels on food products subject to FDA jurisdiction do not have to be reviewed and preapproved by FDA before marketing. Rather, the processor is responsible for properly labeling its products. In fact, FDA officials told us that they do not collect information on how irradiated foods are labeled and marketed. In contrast, USDA reviews and preapproves all labels before use on meat and poultry products and has denied label submissions that do not meet its requirements…FDA does not require the product’s ingredient list to disclose that a particular ingredient has been irradiated, while USDA generally does.

Food Safety: FDA Should Strengthen Its Oversight of Food Ingredients Determined to Be Generally Recognized as Safe (GRAS) (GAO-10-246, February 3, 2010, 69 pages).

FDA only reviews those GRAS determinations that companies submit to the agency’s voluntary notification program…the agency has not systematically reconsidered GRAS substances since the 1980s… FDA has largely not responded to concerns about GRAS substances, such as salt and the trans fats in partially hydrogenated vegetable oils, that individuals and consumer groups have raised through 11 citizen petitions submitted to the agency between 2004 and 2008…FDA’s approach to regulating nanotechnology allows engineered nanomaterials to enter the food supply as GRAS substances without FDA’s knowledge. In contrast to FDA’s approach, all food ingredients that incorporate engineered nanomaterials must be submitted to regulators in Canada and the European Union before they can be marketed.

Food safety note #1: This arrives in the middle of the latest set of FDA recalls, this time of nearly 100 products made with a flavor enhancer, hydrolyzed vegetable protein, contaminated with Salmonella.

Food safety note #2: the Produce Safety Project at Georgetown University has estimated the cost of foodborne illness:  $152 billion annually, of which $39 billion is due to leafy greens and other vegetables.

Food and Drug Administration: Opportunities Exist to Better Address Management Challenges. (GAO-10-279, February 19, 2010, 54 pages).

Through reviewing reports…GAO determined that FDA’s management challenges include recruiting, retaining, and developing its workforce; modernizing its information systems; coordinating internally and externally; communicating with the public; and keeping up with scientific advances…While FDA has taken steps to align its activities and resources to strategic goals, these efforts in its centers and offices are not clear, making it difficult to connect the agency’s use of resources to the achievement of its goals.

If you feel gossipy (or want to interpret the raw data for yourself), you can read what FDA staff actually told GAO interviewers.

Humane Methods of Slaughter Act: Actions Are Needed to Strengthen Enforcement (GAO-10-203, February 19, 2010, 60 pages). [The actual survey responses are here.  And a shorter version given as testimony is here.]

The guidance does not clearly indicate when certain enforcement actions should be taken for an egregious act–one that is cruel to animals or a condition that is ignored and leads to the harming of animals. A noted humane handling expert has stated that FSIS inspectors need clear directives to improve consistency of HMSA enforcement. According to GAO’s survey, FSIS’s training may be insufficient.

This, one can only assume, is an understatement.

The GAO does important work, no?  Now if only government agencies would listen to it.
