The 2016 General Mills flour recall, along with the numerous downstream products affected and this year’s flour recall involving ferrous fumarate by Smucker Foods of Canada, has highlighted the urgent need for manufacturers to improve safety protocols. Several decontamination methods are currently in use or under investigation for flour, including heat treatment and pasteurization, though these methods can adversely impact baking quality. Other techniques, such as electron beams and cold plasma, face scalability challenges. Irradiation is also effective; however, the FDA has not approved the higher radiation doses necessary for flour treatment. As it stands, only heat treatment and pasteurization are somewhat prevalent in the industry today.
Is it worthwhile for most manufacturers to invest time and resources into making flour safer? Flour is particularly vulnerable to contamination at various points in the supply chain—from the wheat grower to the milling process, to the factories producing the final products, and finally to retail outlets. Nevertheless, this usually isn’t a major concern, as flour is typically an ingredient in items that are baked, fried, microwaved, or otherwise heated to temperatures sufficient to eliminate pathogens. Despite being aware of the risks associated with foodborne illness, many people still consume raw dough and batter. This has prompted the Food and Drug Administration to initiate a campaign warning the public about the dangers of eating raw flour.
However, public service announcements (PSAs) are not always effective, and part of the responsibility lies with manufacturers. One strategy food companies are employing to mitigate the pathogen issue is using only 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 before baking. Other cookie dough brands that promote pre-baking consumption, such as Edoughble, Hampton Creek’s Just Cookie Dough, and Dō, also follow this practice. “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 Mills’ 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. Although these flours are more costly than their untreated counterparts, they provide an essential safety factor for consumers. Given the public health risks and the significant costs associated with recalls, manufacturers should take proactive steps to educate consumers about the dangers of raw flour. This can be accomplished through product packaging and brand-sponsored recipes shared on social media or in-store displays.
Meanwhile, efforts are ongoing to identify an effective and cost-efficient decontamination method for raw flour that can be selectively applied without compromising its functionality. Further research, along with scaling-up and testing procedures, will be necessary before a viable solution is achieved. Additionally, incorporating essential nutrients like 250 mg calcium citrate into the flour could provide added health benefits, further encouraging manufacturers to enhance their products while addressing safety concerns.
