Summary: | We examined the rates of pathogenic bacterial cross-contamination from gloves to
meat and from meat to gloves during pork processing under meat-handling
scenarios in transfer rate experiments of inoculated pathogens. The inoculated
pork contained ~5–6 Log10 CFU/g pathogenic bacteria like
Escherichia coli (E. coli),
Staphylococcus aureus (S. aureus),
Listeria monocytogenes (L. monocytogenes),
and Salmonella enterica subsp. enterica
(Sal. enteritidis). On cotton gloves, after cutting the
pork, the cutting board, knife, and cotton gloves showed 3.07–3.50,
3.29–3.92 and 4.48–4.86 Log10 CFU/g bacteria. However,
when using polyethylene gloves, fewer bacteria (3.12–3.75,
3.20–3.33, and 3.07–3.97 Log10 CFU/g, respectively)
were transferred. When four pathogens (6 Log10 CFU/g) were inoculated
onto the gloves, polyethylene gloves showed a lower transition rate (cutting
board 2.47–3.40, knife 2.01–3.98, and polyethylene glove
2.40–2.98 Log10 CFU/g) than cotton gloves. For cotton gloves,
these values were 3.46–3.96, 3.37–4.06, and 3.55–4.00
Log10 CFU/g, respectively. Use of cotton gloves, polyethylene
gloves, knives and cutting boards for up to 10 hours in a meat butchering
environment has not exceeded HACCP regulations. However, after 10 h of use,
3.09, 3.27, and 2.94 Log10 CFU/g of plate count bacteria were
detected on the cotton gloves, cutting board, and knives but polyethylene gloves
showed no bacterial count. Our results reveal the transfer efficiency of
pathogenic bacteria and that gloved hands may act as a transfer route of
pathogenic bacteria between meat and hands. The best hand hygiene was achieved
when wearing polyethylene gloves. Thus, use of polyethylene rather than cotton
gloves reduces cross-contamination during meat processing. |
