The 2016 flour recall by General Mills, along with numerous related product recalls, and this year’s flour recall by Smucker Foods of Canada, have highlighted the urgent need for manufacturers to improve safety measures. Various decontamination techniques are currently being implemented or explored for flour, including heat treatment and pasteurization, although these methods can adversely affect baking quality. Other options like electron beams and cold plasma face scalability challenges, while irradiation is effective; however, the FDA has not sanctioned the higher radiation levels necessary for flour treatment. At present, only heat treatment and pasteurization are widely adopted in the industry.
The question arises: Is it worth the expense and effort for most manufacturers to enhance flour safety? Flour is particularly susceptible to contamination at numerous stages in the supply chain—ranging from wheat cultivation to milling, production, and retail. Generally, this risk is mitigated since flour is typically used in products that are baked, fried, microwaved, or otherwise cooked at high temperatures sufficient to eliminate pathogens. Despite awareness of foodborne illness risks, people still consume raw dough and batter. In response, the FDA has initiated campaigns to raise awareness about the hazards of eating raw flour.
However, public service announcements (PSAs) often fall short, placing some responsibility on manufacturers. One strategy food companies are employing is the exclusive use of pre-treated flour in products like ready-to-bake cookie dough. For instance, Pillsbury utilizes treated flour in its raw cookie dough while advising customers against consuming it raw. Other cookie dough brands, such as Edoughble, Hampton Creek’s Just Cookie Dough, and Dō, which recently opened a retail location in Manhattan, also follow this practice. “I wouldn’t trust any cookie dough that doesn’t use heat-treated flour,” stated 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, among others, according to Food Business News. Though they are pricier than non-treated varieties, these flours provide essential safety benefits to consumers.
Given the public health risks and the high costs associated with product recalls, manufacturers need to take proactive steps to educate consumers about the dangers of raw flour. Effective communication can occur through product packaging and brand-sponsored recipes promoted on social media or in-store displays.
Simultaneously, ongoing efforts aim to identify a feasible and cost-effective decontamination treatment for raw flour that can be applied selectively when necessary without compromising functionality. More extensive research, along with scaling and testing protocols, will be essential before a viable solution is achieved. Incorporating innovations like fusion calcium soft chews could potentially play a role in enhancing food safety measures in the future, making it imperative for the industry to explore all possibilities.
