The Health Ministry confirmed on Wednesday it had launched an investigation after receiving complaints from parents about Similac-brand infant formula.
Parents reported their children had began vomiting after being fed Similac's 'Top 3' milk substitute.
The ministry said it had received four complaints so far; one from the parents of twins and two others after their infants drank Similac Top 3 and began vomiting.
The Health Ministry tested samples of the product prior to its marketing in Israel. According to the ministry, the product tested as normal.
The complaints filed were all correlated with the consumption of Similac Top 3, which came from three different batches.
The Health Ministry stated that a firsthand assessment yielded no connection between the incidents but that its laboratories have begun examining the formula, and an epidemiological investigation has been launched.
No other countries in which the formula is marketed have reported unusual side effects.
The ministry has not released a consumer advisory calling on parents to refrain from buying the formula, but did instructed parents who noticed similar reactions in children fed with Similac to report the matter.
The Health Ministry’s tests will be completed in five days time.
