How a Dairy Brand Turned Milk Cartons Into a Nationwide Search Party
Brazil’s missing persons crisis is not new, but the scale makes it hard to manage. Families rely on public attention to keep searches active, so most campaigns depend heavily on digital platforms. This creates a blind spot in areas with limited internet access and reduces how often people actually see those faces.
Piracanjuba, one of Brazil’s largest dairy brands, looked at that gap and found a simple solution. Its products already reach about 98 percent of households across the country, including regions where online campaigns are barely visible. Instead of asking people to go looking for information, the brand brought the search directly into everyday routines.
Turning Packaging Into Media
The idea behind “Missing PortrAIts,” launched on February 19, 2025, was straightforward. If milk cartons show up in millions of homes every day, they can carry more than product information; they can carry faces.
Piracanjuba partnered with Mães da Sé, a leading organization that supports families of missing persons, and worked with agency Ampfy to build the campaign. The plan turned every carton into a point of contact between the public and an active search effort.
About 300 million milk cartons became part of the initiative.
Updating Faces With AI And Expert Input

One major challenge in missing person cases is the passage of time. Many available photos are years old, which makes recognition more difficult. The campaign addressed this by using an AI method called Probabilistic Image Synthesis.
The system analyzed family traits and aging patterns to generate updated portraits that reflect how individuals might look today. A criminal expert reviewed and worked alongside the AI to ensure the images remained realistic and useful.
AI expert Hidreley Diao contributed to refining these outputs by helping bridge the gap between raw data and something people could recognize in real life. The updated images were then printed directly onto Piracanjuba’s packaging.
Placing Faces in Important Places
The distribution was not random. The cartons were sent to supermarkets near the last known locations of each missing person. Someone picking up milk in a familiar neighborhood might come across a face tied to that same area. That connection increases the likelihood of recognition and makes the campaign relevant.
Early Results Show Real Impact

The campaign moved quickly once it launched, and within the first month, eight families were reunited with their missing relatives. The outcome gave the project immediate credibility and showed that the approach could work at scale.
Ivanise Esperidião da Silva, president of Mães da Sé, highlighted the campaign’s reach, noting that a brand of this size brought a level of visibility the organization had not experienced before. The results also proved that when awareness meets the right placement and updated information, it turns into action.
A Search Effort That Keeps Expanding
“Missing PortrAIts” is still in its first phase, and there is no set end date. Piracanjuba’s marketing director, Lisiane Campos, confirmed that the company is already planning future updates and additional waves of images.
More portraits will be introduced over time, and the network of cartons will continue to circulate across the country. Each new cycle adds fresh opportunities for recognition and response.
Information about the individuals featured in the campaign is also available through Piracanjuba’s dedicated page, along with updates shared through Mães da Sé’s social channels.
