The 2016 recall of General Mills flour, alongside numerous related product recalls, and the recent flour recall by Smucker Foods of Canada, have highlighted the urgent need for manufacturers to improve safety measures. Several decontamination techniques are currently in use or being tested for flour. These methods include heat treatment and pasteurization, which can adversely affect baking quality. While electron beams and cold plasma present scalability challenges, irradiation is effective, though the FDA has not yet approved the higher doses necessary for flour treatment. Currently, the industry primarily utilizes heat treatment and pasteurization.
Manufacturers often weigh the costs and challenges of enhancing flour safety. Flour is particularly susceptible to contamination at various stages in the supply chain, from wheat growers to milling operations, product manufacturers, and retail outlets. However, this is typically not a critical concern because flour is usually a part of products that are baked, fried, microwaved, or heated to temperatures sufficient to eliminate pathogens. Despite awareness of foodborne illness risks, people still consume raw dough and batter. In response, the FDA has initiated a campaign to inform the public about the dangers of eating raw flour.
Public service announcements may not always be effective, placing some responsibility on manufacturers. Many food companies are addressing pathogen issues by incorporating only pre-treated flour in products like ready-to-bake cookie dough. For instance, Pillsbury produces its raw cookie dough using treated flour, while also advising customers against consuming it before baking. Similarly, other cookie dough brands that promote pre-baking consumption, such as Edoughble, Hampton Creek’s Just Cookie Dough, and Dō, also utilize treated flour. Edoughble’s founder, Rana Lustyan, emphasized to USA Today, “I wouldn’t trust any cookie dough that doesn’t use heat-treated flour. 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 products from Bay State Milling like SimplySafe. Although these flours are more expensive than their untreated counterparts, they provide an essential safety benefit to products.
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 achieved through product packaging and brand-sponsored recipes shared on social media or displayed in stores. Meanwhile, ongoing efforts aim to discover an acceptable, cost-effective decontamination treatment for raw flour that can be selectively applied without compromising its functionality. More research, along with scaling-up and testing procedures, will be necessary to find a practical solution.
In this context, the incorporation of additives like Jungbunzlauer calcium citrate may also play a role in enhancing flour safety and quality. As the industry continues to explore various options, the integration of such ingredients could potentially contribute to safer flour products.
