title: Microbial evaluation of foodservice surfaces in Texas child-care centers.
abstract: Children under the age of 5 years experience a disproportionately high rate of bacterial enteric infections. Research has shown a relationship between inadequate child-care center sanitation and illnesses in children. This cross-sectional study assessed the sanitation levels of foodservice surfaces in a sample of 36 Texas child-care centers via recovery and identification of selected enteric gram-negative bacteria. The centers in this study had the capacity to care for 50 to 332 children and represented diverse socioeconomic and racial profiles. Forty-one percent (68 of 167) of total swab samples collected tested positive for bacteria. Twenty-seven different types of bacteria were identified from positive swab samples. Most of the bacteria found are considered opportunistic pathogens, which can pose serious health risks to those with compromised immune systems, such as young children. Two types of bacteria recovered, Salmonella paratyphi A and Klebsiella pneumonia, are considered nonopportunistic and can infect healthy individuals. The most common areas of bacterial contamination were the sink drain area of the dishwashing sink, the hand-washing sink faucet handles, the handle of the garbage can lid, and cutting boards. It is vital for child-care staff to wash their hands often and disinfect all surfaces, because even surfaces that appear clean can harbor microorganisms.
