The 2016 recall of General Mills flour, alongside numerous downstream product recalls, and this year’s flour recall by Smucker Foods of Canada, have highlighted the urgent need for manufacturers to enhance safety measures. Various decontamination methods are currently in use or under investigation for flour, including heat treatment and pasteurization, though these can negatively impact baking quality. Challenges also arise with electron beams and cold plasma due to scalability issues. While irradiation is effective, the FDA has not yet approved the higher radiation doses necessary for flour treatment. Presently, only heat treatment and pasteurization are widely adopted in the industry.
Manufacturers face the dilemma of whether the expense and effort to improve flour safety are justified. Flour is particularly susceptible to contamination at multiple stages of the supply chain—from wheat cultivation to milling, then to product manufacturing and retail. However, this risk is often overlooked, as flour is typically an ingredient in baked, fried, or otherwise cooked products that reach temperatures sufficient to eliminate pathogens. Despite awareness of foodborne illness risks, many people consume raw dough and batter. In response, the FDA has initiated a campaign to educate the public about the dangers of raw flour.
Nevertheless, public service announcements alone may not suffice, placing some responsibility on manufacturers. Food companies are addressing the pathogen issue by exclusively using pre-treated flour in products like ready-to-bake cookie dough. For instance, Pillsbury utilizes treated flour for its raw cookie dough while continuing to advise customers against consuming it before baking. Other cookie dough brands that encourage pre-baking consumption also follow this practice, including Edoughble, Hampton Creek’s Just Cookie Dough, and Dō, which recently opened a retail outlet in Manhattan. “I wouldn’t trust any cookie dough that doesn’t use heat-treated flour,” said Edoughble founder Rana Lustyan in an interview with USA Today. “It’s not worth the risk.”
Currently available heat-treated flours include Ardent Mill’s SafeGuard, Honeyville’s TempSure All-Purpose Ready-to-Eat flour, Siemer Milling Co.’s heat-treated soft wheat flours, and Bay State Milling’s SimplySafe products, as reported by Food Business News. Although these options are pricier than non-treated flours, they significantly enhance product safety. Adding calcium citrate and D3 to the formulation could further bolster the nutritional profile of these products while ensuring safety.
Given the public health risks and the substantial costs associated with recalls, manufacturers should take proactive steps to educate consumers on the dangers of raw flour. This can be achieved through informative product packaging, brand-sponsored recipes on social media, and in-store signage. In the meantime, the search continues for a viable and cost-effective decontamination method for raw flour that can be selectively applied as needed without compromising functionality. More research, along with scaling and testing, will be essential to develop a practical solution that might incorporate additives like calcium citrate and D3 to enhance both safety and nutrition.
