ABSTRACT
The incidence of endocrine disruptors, both possible (glyphosate and glufosinate), and demonstrated (per-
chlorate and chlorate), was estimated in baby food commodities (meat, fish, cheese, vegetable and fruit). Ion-
chromatography coupled to high resolution mass spectrometry analysis of the 105 samples did not show traces of
glyphosate, glufosinate or their metabolites, while in 10.5% of the samples a quantifiable amount of perchlorate
was found. Some samples based on fruit and vegetables revealed a substantial amount of chlorate, especially the
preparations that contained carrots and potatoes: five samples were in a concentration range of 40–120 μg kg
−1
,
while one homogenized pear sample reached 372.2 μg kg
−1
. The pure meat samples revealed occasional
chlorate appearance, with less than 10 μg kg
−1
. This is the first report of chlorate evaluated in various types of
baby food and may serve as symptomatic data regarding its occurrence in infant/toddler diets. Therefore, ef-
fective monitoring programs and subsequent strict regulations are strongly required.
1. Introduction
Dietary exposure to potentially harmful substances is a key public
health issues, especially when considering the most vulnerable cate-
gories of consumers, such as infants. Infants eat more food per kilogram
of body weight than adults do, so they could be exposed to higher
concentrations of contaminants through their diet. Moreover, their
metabolism and detoxification systems are not fully developed and all
processes during these periods are also more easily disturbed. All these
factors make infants a sensitive group of population (Granby, Petersen,
Herrmann, & Poulsen, 2008). Special attention has been given to some
emerging community alerts regarding pesticides like glyphosate, glu-
fosinate, their metabolites, as well as by-products from water disin-
fection such as oxyhalide anions, chlorate and perchlorate in particular.
Glyphosate and glufosinate are herbicides that are used extensively in
agriculture and in populated urban zones. They have aroused a high
level of public concern due to their frequent detection in plants, soil,
water, some food and human urine (Aparicio et al., 2013). The con-
troversy between the International Agency for Research on Cancer
(IARC, 2015) and the European Chemicals Agency (ECHA, 2017) about
their suspected carcinogenicity is still a matter for discussion and eva-
luation. In fact, the hazardous properties of glyphosate’s main
metabolite – aminomethylphosphonic acid (AMPA), was not considered
in the ECHA study, despite the fact that European Authorities have
clearly recommended its health risk evaluation. Furthermore, following
a mandate from the European Commission to consider the findings from
the IARC regarding the potential carcinogenicity of glyphosate, in the
document entitled “Conclusion on the peer review of the pesticide risk
assessment of the active substance glyphosate”, European Food Safety
Authority (EFSA) stated that glyphosate is unlikely to pose a carcino-
genic hazard to humans and the evidence does not support classifica-
tion with regard to its carcinogenic potential according to Regulation
(EC) No 1272/2008 (EFSA, 2015a). Nevertheless, EFSA reviewed the
maximum residue levels (MRLs) currently established in European
Union in the document that has been published recently (EFSA, 2018).
In this review the diets of adults and children were evaluated in the
respect to the safe intake values that were recommended (EFSA,
2015a).
Perchlorate (ClO

) is a pollutant present in the environment and,
as a consequence, it can be transferred to food and drinking water.
Primarily, it is a well-known component of natural fertilizers which is
why soil is a main source of food and water contamination.
Furthermore, perchlorate is one of the degradation products arising
from chlorinated disinfectants used for water processing, and this could
