Formula Gaps Are Back, and Fewer People Are Talking About It
Two years after the infant formula crisis dominated headlines and sparked congressional hearings, a quieter version of the same problem is taking shape across the country. WIC participants – low-income families, pregnant women, and infants who rely on the federal nutrition program – are again running into empty shelves, store rejections, and brand substitutions that their pediatricians haven’t approved. The cause this time isn’t a single factory shutdown. It’s a structural one: state WIC vendor contracts are lapsing, and the rebidding process is creating supply gaps that the program’s architecture was never built to handle smoothly.
WIC operates through a state-by-state exclusive contract system, where each state selects one formula manufacturer – typically Abbott, Mead Johnson, or Nestle – to supply subsidized formula in exchange for rebates paid back to the government. When those contracts expire and states open new bids, the transition period is rarely clean. Retailers must update their systems, manufacturers must ramp up distribution, and families must adjust to new products, often mid-feeding schedule. When any part of that chain stutters, the families with the least flexibility absorb the disruption.
How the Contract System Creates Its Own Volatility
The exclusive-contract model exists for a sound financial reason: the rebates states collect from winning manufacturers fund a substantial portion of the WIC program itself, reducing the federal cost of providing benefits. The tradeoff is concentration. When one brand wins a state contract, that brand must supply formula for every WIC-enrolled infant in the state. If the manufacturer can’t meet that demand fast enough after a new contract kicks in, or if retailers haven’t yet updated their point-of-sale systems to reflect the new approved product list, participants get turned away at checkout.
That checkout rejection is more consequential than it sounds. WIC benefits don’t roll over in the way grocery store gift cards do. Families who can’t purchase formula during a given month because their local store’s system isn’t updated, or because the newly contracted brand is backordered, often lose that benefit window entirely. The program’s monthly structure was designed for stability, not for the friction that comes with contract transitions happening on rolling schedules across 50 different state systems.
Several states have quietly moved through contract renewals in the past several months, with transitions creating uneven availability at the retail level. The problem tends to cluster in rural areas and smaller grocery chains where formula inventory is thin to begin with and system updates happen slower. A large urban retailer with a dedicated WIC coordinator can adapt within days. A small independent grocer in a rural county often can’t – and the families shopping there don’t have a backup option.
Pediatricians Caught in the Middle
When a state’s WIC contract switches from one brand to another, families don’t automatically receive guidance from their child’s doctor. Pediatricians are notified through public health channels, but the lag between official notice and clinical awareness can stretch weeks. In that window, parents show up to appointments holding a new formula they’ve never used and a benefits card that won’t scan correctly at their usual store, asking for reassurance their doctor isn’t yet positioned to give.
For infants with specific dietary needs – those managing reflux, allergies, or premature birth complications – a forced brand switch carries real medical weight. Formula isn’t interchangeable the way generic medications can sometimes be. Protein sources, carbohydrate blends, and caloric density vary across brands, and what works for a healthy full-term infant may cause digestive distress in a more vulnerable one. Pediatric nutrition decisions made during contract transitions are being made under pressure, not under ideal clinical conditions.
The Policy Gap Nobody Fixed After 2022
The 2022 shortage prompted emergency legislation, regulatory waivers, and a national conversation about formula supply chain fragility. What it didn’t produce was a structural fix to the WIC contract model. Congress extended some flexibility measures that allowed states to temporarily broaden which formulas WIC benefits could cover, but those measures were designed as emergency tools, not permanent policy. As the memory of the crisis fades, so has the urgency to hardwire those flexibilities into the standard program rules.
The result is that the system is still operating the same way it always has – one state, one manufacturer, one transition period that occasionally fails the people it’s supposed to serve. State WIC agencies do maintain contingency plans, and the USDA has issued guidance encouraging states to build in longer transition periods when switching contracts. But guidance isn’t the same as a mandate, and a longer transition still doesn’t solve the inventory problem if the incoming manufacturer hasn’t scaled production to meet the new contract volume.
There’s a broader budget dimension here as well. States are navigating tight fiscal environments across multiple program areas. The rebate revenue that flows from exclusive formula contracts makes those arrangements financially attractive, which means states have real incentive to stick with the model even knowing the transition risks. Abandoning exclusivity in favor of a multi-brand WIC system would likely reduce rebate revenue and put pressure on state WIC budgets that are already operating with little margin. The math of the program creates its own gravity toward the very structure that generates the gaps.
WIC currently serves roughly 6 to 7 million participants nationally, with formula benefits making up a significant share of the infant nutrition component. Families enrolled in the program are, by definition, families for whom market-rate formula is not consistently affordable – meaning the gap between a WIC benefit and a household’s own purchasing power is not a small one. When the program stutters, there’s no obvious financial cushion waiting. Some families are stretching formula by watering it down, a practice with serious nutritional consequences for infant development. That’s not a new phenomenon in periods of shortage, but it’s one that tends to go unrecorded until a pediatrician or emergency room catches it downstream. The current disruption hasn’t reached crisis scale, but it doesn’t need to be a crisis to cause harm.
