Listeria monocytogenes is among the most important foodborne pathogens. It may enter food-processing environments through raw materials, handlers or equipment and may persist due to ineffective cleaning or sanitation. The bacterium can be isolated from both frozen vegetables and fresh food substances. This study aimed to estimate the prevalence of L. monocytogenes in spices and frozen vegetables and screen for some virulence factors and drug-resistance determinants of the isolated bacteria. First, conventional microbiological methods were used for the isolation and identification of bacteria. Next, the identity of isolated bacteria was confirmed by molecular techniques, and the virulence genes iap and hlyA were identified by real-time polymerase chain reaction (PCR). The hemolytic activity of the isolates was assessed by cultivation on sheep blood agar. Furthermore, the antimicrobial susceptibility of confirmed L. monocytogenes isolates was tested by the disk diffusion method against 10 antibiotics. Out of 331 vegetable samples, 47 isolates were confirmed to contain L. monocytogenes, whereas none of 40 spice samples tested positive. All isolates were positive for iap and hlyA genes. Susceptibility testing indicated that all isolates were sensitive to trimethoprim/ sulfamethoxazole, but only 36% were sensitive to penicillin G, while 100% and 70% showed intermediate resistance to chloramphenicol and erythromycin, respectively. All tested isolates were resistant to amoxicillin, gentamicin and norfloxacin; on the other hand, 90, 86 and 84% of the tested strains were resistant to ciprofloxacin, ceftazidime/clavulanic acid and amikacin, respectively. In summary, L. monocytogenes isolates disseminated in frozen vegetable samples from the Egyptian market were highly virulent, entirely multiple-drug resistant and were enriched in iron-containing vegetables. Since L. monocytogenes is primarily pathogenic to humans and causes a life-threatening disease, there is a potential infection risk for people who usually deal with frozen vegetables before cooking. Hence, surveillance to L. monocytogenes in frozen products, together with implementation of tight measures would be valuable in preventing listeriosis, and are highly recommended.

Common disinfectants used in chiller tanks and dipping stations at poultry processing plants are not effective against Salmonella in its biofilm state, caution Tereza Chylkova and colleagues at the University of California–Davis. [1]

Salmonella biofilms aren’t as pathogenic as free-floating Salmonella particles but, nevertheless, are significant contributors to contamination in food processing plants. However, there’s no established way to measure the sensitivity of biofilms to specific disinfectants.

Consequently, the researchers tested the effectiveness of disinfectants used by commercial poultry companies against Salmonella biofilms.

Raw milk plays an important role in the survival and transport of pathogenic bacteria including Escherichia coli strains. This study was performed to determine the existence of E. coli in raw milk intended for human consumption and its associated virulence determinants. In this context, a total of 232 milk samples were obtained from different dairy shops located at Mansoura city and its surrounding villages. Milk samples were subjected for bacteriological and serological examination of E. coli. Furthermore, E. coli strains were tested for its haemolytic activity on blood agar plates. The recovered E. coli strains were also screened by Polymerase chain reaction (PCR) for the presence of enterotoxins including heat –labile (LT), heat- stable (ST) toxins and haemolysin (hly) genes. The recovery rate of E. coli was 14.65% (34/232). Among the recovered E. coli strains, 12 different E. coli serotypes were identified namely, O26:H11 (n꞊6), O111:H2 (n꞊5), O128:H2 (n꞊5), O91:H21 (n꞊4), O124 (n꞊3), O127:H6 (n꞊3), O103:H21 (n꞊2), O153 (n꞊1), O113:H4 (n꞊2), O6 (n꞊1), O121:H7 (n꞊1) and O146 (n=1). Regarding PCR results, 31(91.19%) E. coli strains harbored STa and seven strains carried hly gene (20.59%) while non E. coli isoates harbord LT gene. Conclusively, raw milk can be considered as serious source of pathogenic E. coli, therefore, proper management practices and effective control measures are recommended to improve milk hygiene and sanitation.

KAKINADA: A teenager died of food poisoning while undergoing treatment at government general hospital (GGH) here on Wednesday.

He was identified as Nalla Pandu (16). Five other persons were shifted to government hospital in Kakinada on Tuesday evening after their condition turned critical.
GGH superintendent Dr. Raghavendra Rao said 13 persons have been admitted to the hospital from CHC (Community Health Centre), Jaggampeta on Wednesday evening. He further said the condition of one person is critical.

It may be recalled here that 35 persons took ill after they had breakfast from a hotel at Ramavaram village in Jaggampeta mandal.
