The students who used the cafeterias in the public schools of the City of Buenos Aires ate expired, almost raw food and, in some cases, food that had been banned for commercialization by the Department of Hygiene and Food Safety. According to a report by the Auditor General of the City (AGCBA, for its acronym in Spanish) the meal service, lunch, milk, refreshments and snacks that the Directorate of Cooperatives and Cafeterias provided in 2006 presented "serious irregularities" and several breaches of the concession contract.

The watchdog found "inadequate cooking temperatures" in 21% of the meat analyzed, both red and white. For example, in School No. 7 San Cristobal, it was verified that the firing temperature in the center of the meat was 67.6º C, "when the Bidding Terms and Conditions says it is set to be 80 °C, until the disappearance of pink juices", says the report, adding that almost half of the students rejected the dish. Furthermore, the AGCBA said there was improper storage temperatures detected in 35% of the 110 other foods that was sampled.
Moreover, the Directorate of Cafeterias did not get a food supplement for children between 9 months and 3 years old of the Sun Garden Nursery and Infant School No. 3 of La Boca, as they should have. The supplement is used for children with a deficit of weight that could affect their normal growth.
What they did get was a milk brand "La Muneca", which had been withdrawn from marketing in 2005 by Health and Food Safety. It was at the No. 16 Flores School and, therefore, the AGCBA recommended both that agency and the Directorate of Cafeterias, "join mechanisms to control the brands and quality of products delivered by tenderers". Also, on August 30, 2006 in the cupboards of the kitchen of Collegiate School No. 7, the inspection body ran into packs of whole milk fluid, UAT, with an expiration date 17/03/06, i.e. they could no longer be eaten, because they represented a health risk, 166 days earlier.
Regarding refreshments, regulations require that the date of manufacture and expiry be specified, and that they be transported in "an insulated container of material which ensures the chain of cold or heat is intact". The AGCBA observed that 100% of the cases analyzed do not meet any of the requirements: they have labels detailing the deadlines to be consumed, and are transported in plastic baskets that do not maintain the adequate temperatures.
Another irregularity occurred in the weight (actual weight in grams) of food. In this case, 91% of the 103 analyzed was prepared dishes with lots of ingredients that were not the right ones.
