Understanding Oatly Milk Production and Pasteurization
To understand Oatly's safety, it's helpful to know how it's made. Oat milk is produced by soaking oats in water, blending them, and then straining the liquid. Commercial brands like Oatly then fortify this liquid with vitamins and minerals to enhance its nutritional profile.
A critical step for all commercial oat milk is pasteurization. This process involves heating the milk to a specific temperature for a set time to kill harmful bacteria and extend its shelf life. This ensures the product is microbiologically safe for consumption when it leaves the factory. For Oatly, this process is standard for shelf-stable products, but the safety of the entire supply chain, especially with external partners, must be considered.
Past Recalls and Contamination Concerns
While Oatly is generally safe, the brand has been involved in notable recalls that sparked consumer concern:
- 2022 Lyons Magnus Recall: In August 2022, Oatly was included in a large-scale recall initiated by Lyons Magnus, a co-packer that manufactured several beverages for various brands. The recall was due to potential contamination from Cronobacter sakazakii, a bacteria that can cause infections, particularly in vulnerable populations. Following the incident, Oatly stated they terminated their business relationship with Lyons Magnus and emphasized that the well-being of their consumers was the utmost priority.
- 2019 Metal Particle Recall: In March 2019, Oatly recalled a specific batch of its chilled Oat Drink in the UK due to fears of small metal particles from a broken machine part. This was a proactive measure, with the company emphasizing the risk was very small, and no other products were affected.
These recalls highlight that while major brands implement strict safety protocols, risks can arise from external manufacturing partners or machinery failures. It is essential for consumers to stay informed about product recalls by checking official food safety agency websites like the FDA.

Scrutinizing Oatly's Ingredients
Beyond bacterial risks, some critics have raised concerns about certain ingredients in Oatly, primarily added oils and phosphates:
- Rapeseed Oil: Rapeseed oil (canola oil in the US) is used to give Oatly a smooth, creamy texture and to add unsaturated fats. While generally recognized as safe, some critics link it to potential inflammation. However, its inclusion allows Oatly to match the texture of dairy milk more closely without adding high levels of saturated fat.
- Phosphates (Dipotassium Phosphate, Tricalcium Phosphate): These are used as acidity regulators and stabilizers to prevent the milk from curdling in coffee. While safe for most, some health experts suggest people with advanced chronic kidney disease should monitor their phosphate intake from processed foods. Oatly's organic versions contain fewer ingredients, often omitting these additives.
It is important to remember that most commercial food products contain additives for quality and stability. For those with specific health concerns, reading the ingredient list is always the best practice.
Glycemic Index and Blood Sugar Spikes
One of the most widely discussed health aspects of oat milk is its potential impact on blood sugar. The manufacturing process uses enzymes to break down the oat's natural starch into sugars, primarily maltose, which has a high glycemic index (GI). This can lead to a more significant blood sugar spike than whole oats.
- For Diabetics: Individuals with diabetes or prediabetes should be mindful of their intake. While fortified versions add nutrients, the carbohydrate profile might be less suitable than lower-carb alternatives like almond milk. Choosing unsweetened varieties can help minimize added sugar intake.
- For the General Population: For a healthy individual with a balanced diet, a single serving of oat milk is unlikely to cause a concerning blood sugar response. The glycemic load (GL) is often considered low, especially when consumed as part of a meal.
Oatly and Dietary Restrictions: Gluten and Lactose
Oatly is naturally free of lactose and dairy protein, making it a safe and popular choice for those who are lactose intolerant or following a vegan diet. However, those with gluten sensitivity must be cautious.
- Gluten: Although oats are inherently gluten-free, cross-contamination with gluten-containing grains (wheat, barley, rye) during processing is a risk. For this reason, Oatly products are not marketed as gluten-free in some regions like Europe. However, in the US, Oatly uses certified gluten-free oats, ensuring safety for those with celiac disease or gluten intolerance. Consumers should always check the label for certification.
