Abstract
BACKGROUND
Soybean and maize are the most cultivated genetically modified (GM) plants. Because of the increase in the imports of GM products to Iran, infant formula and baby food, which is consumed by babies during their first month of life, can also contain soybean and maize. It has become fundamental to screen these types of products.
OBJECTIVES
The present study aimed to investigate the GM corn and soybean in baby food and infant formula using real-time polymerase chain reaction (PCR).
METHODS
A total of 60 baby food and infant formulas were collected randomly from the local drugstores in Tehran. Genomic DNA was extracted from all samples, then by real-time PCR detection, tested Pat/NOS. Internal control genes zein and lectin were used for maize and soybean, respectively.
RESULTS
Results showed that 5% of infant formulas and 5% of baby food, two Iranian and one imported baby food, and two imported and one Iranian infant formula were positive for pat. However, NOS was detected in none of the samples. The results showed positive results for the presence of the pat gene in the products without an appropriate label.
CONCLUSIONS
This article provides evidence of GM maize and soybean presence in baby food and infant formula in Iran.
