a2 Milk Co. ( ACOPF ) is under fresh pressure after recalling three batches of its a2 Platinum USA-label infant formula sold in the US, following the detection of cereulide, a toxin linked to vomiting and diarrhea. The recall, which began on May 1, was initiated after manufacturer Synlait Milk Ltd. identified the toxin through additional testing following new guidelines from New Zealand's Ministry for Primary Industries in mid-April. The company said the issue is limited to the US and does not affect China, its most lucrative market, while no confirmed incidents of infant illness or harm have been reported. Even so, the development lands in a global baby formula market already shaken by contamination concerns, after Nestle SA widened a recall in January tied to cereulide in an ingredient from one of its suppliers, while Danone SA and Groupe Lactalis have also recalled hundreds of batches across dozens of countries.
For investors, the timing could be the bigger problem. a2's shares had already fallen almost a third over the past month after the company cut revenue and earnings guidance, citing shipment delays to China partly linked to the Iran war. The recall added another hit to sentiment, with the shares dropping as much as 19% in Wellington, the company's steepest one-day decline since August 2024, before paring losses to around 10%. That move suggests investors may be weighing not only the limited size of the recall, but also the risk that a safety-related headline could possibly damage brand confidence in markets where infant formula trust is a critical part of demand.
The company said the recalled product has a different formulation from formula sold in Australia, New Zealand, South Korea, Vietnam, and China, a distinction also highlighted by Citigroup analyst Sam Teeger in Sydney. Still, Teeger warned that the recall could make its way onto Chinese social media and potentially hurt the brand, while supply chain constraints may persist longer than expected and winning back consumers who switch to rival brands may not be easy or cheap. China's customs administration said none of the recalled products had been imported into the country through general trade channels, and Chinese social media users have so far shown limited concern, with some posters pointing to differences between products sold in different markets. The recall covers a relatively small quantity of three batches totaling 63,078 tins, including an estimated 16,428 tins sold to consumers, while importation rights ended on Dec. 31 last year and the product had already been discontinued and removed from sale before the recall.
