Making Food Additives Safe For Consumers

Consumer Safety

Consumers Need Better Information: “What is food to one man is bitter poison to others,” Lucretius says.

Aarticle in Nature News says that allowing manufacturers to decide if food additives are safe is not a good idea, often leading to not only conflicts of interests but also poor science and poor consumer safety. Independent analysis is necessary.

The article says:
A chef who crafts a delicacy for sale in the United States can choose from more than 10,000 food additives to garnish the dish. Of these chemicals, 43% are labelled ‘generally recognized as safe’ (GRAS) and need not be approved by the US Food and Drug Administration (FDA).
The system has weaknesses. A manufacturer is responsible for assessing whether an additive it has developed is GRAS. Once that is done, the manufacturer is asked — but not required — to notify the FDA. There are no data to evaluate compliance systematically, but the FDA found during a 2010 crackdown on caffeinated alcoholic drinks that four out of four manufacturers queried had not done the required checks.
Even when manufacturers do submit GRAS determinations, there are concerns about the quality of the assessment. An ongoing project at the Pew Charitable Trusts in Washington DC reveals discomfiting gaps in the data. A search of three toxicological databases, including that of the FDA, showed that fewer than 38% of GRAS claims were backed up by FDA-recommended toxicology studies in animals (T. G. Neltner et al. Reprod. Toxicol.http://dx.doi.org/10.1016/j.reprotox.2013.07.023; 2013).
The same team has published an analysis of 451 GRAS notifications submitted to the FDA. To avoid conflicts of interest, assessments should be done by an independent expert panel, but none had been; in fact, 22% had been performed by an employee of the manufacturer (T. G. Neltner et al. JAMA Intern. Med. http://doi.org/nd5; 2013).
This is poor policy; if manufacturers want the public to have confidence in their products the onus is on them to show impartiality, in keeping with scientific standards and objectives. The first rule of production is not to sell shoddy products and services, as is now often the case, but to sell the best products that current manufacturing and production technologies allows. No sensible person begrudges companies making a good profit if that follows making a good product.
