Heavy metals within infant formula can pose large risks for infants if consumed in amounts above those levels deemed safe by regulators. This challenge by regulators on testing laboratories to enforce these strict legislative limits adds pressure for laboratories to provide accurate testing across a range of contaminants within both infant formula and other matrices.This strict regulation requires effective and accurate testing capabilities, which through proficiency testing can be maintained or achieved. Infants are particularly at risk in their developmental stages of life.Heavy, toxic metals such as Aluminium, Cadmium, Chromium, Iodine, Molybdenum, Selenium, Tin and Nickel are often found in food, either as a natural contaminant or a contaminant from production. Their effects are various and far reaching, such as inhibiting nutrient absorption in the case of cadmium.The large degree of nutritional importance focussed on infant formula puts a great deal of emphasis on the accurate testing ability of your laboratory to detect and quantify any contaminants within foodstuffs. This risk of contamination is increased owing to the number of ingredients within infant formula, to achieve the correct nutritional values claimed.To achieve this, effective testing, backed by strong proficiency testing results, must be utilised. Fapas proficiency tests can benchmark your current testing performance, and by providing a snapshot of your testing ability, highlight key areas of improvement from which to build on your current testing capability and provide accurate testing for your customers.
