Background: Cronobacter sakazakii is associated with illness in infants from contaminated powdered infant formula (PIF) and it is frequently recovered from PIF factory environment. Limited information is available on contamination of other food such as dairy and meat products in Libya. Methods and findings: A total of 261 samples of milk, dairy products and coarse ground meat products were collected from different localities in Libya. Samples were examined for Cronobacter spp. with an adapted ISO /DTS 22964 cultural protocol using HiChrome™ Enterobacter sakazakii modified agar coupled with 16S rDNA partial sequencing to identify the organism. The identified isolates were biochemically characterized and tested for their ability to produce yellow pigment. Out of the 261 analyzed samples, only two beef burgers, one fermented milk “Laban”, one she-camel’s milk, two raw cow’s milk, two cereal baby food, one Maassora cheese and one ready to feed baby milk were contaminated with Cronobacter spp. at a total rate of 3.8%. Accuracy of HiChrome Ent. sakazakii modified agar reach 100% as all of blue-green presumptive colonies were confirmed Cronobacter spp. while other colorless, greenish or with blue center colonies which competed growth with Cronobacter spp. were predominantly Escherichia coli followed by Klebsiella spp. and to less extent Pseudomonas luteola, Citrobacter freundii and Acinetobacter baumanii. Moreover, the isolated strains of Cronobacter were resistant to Amoxicillin, Erythromycin, Vancomycin and Streptomycin, and sensitive to Doxycycline, Enrofloxacin and Gentamycin. Conclusion: This study documents for the first time the occurrence of Cronobacter spp. in beef burger, raw cow’s milk, fermented milk “Laban”, she-camel’s milk, Maassora cheese, cereal baby food and ready to feed baby milk sold in Libya, by using conventional methods, biochemical tests and molecular techniques.

Background and Aim: Foodborne illnesses are a serious challenge to human health and the economic sector. For example, salmonellosis remains a burden in developed and developing nations. Rapid and reliable molecular methods to identify Salmonella strains are essential for minimizing human infection. This study aimed to identify Salmonella spp. in raw milk and dairy products using conventional and molecular techniques and to test the antibiotic susceptibility of the isolated strains. Materials and Methods: One hundred and thirty-one milk and dairy product samples were randomly collected from different localities in Libya. Samples were examined for the presence of Salmonella by conventional culture techniques, including cultivation in Rappaport-Vassiliadis broth and streaking on xylose lysine deoxycholate agar. Identification also used polymerase chain reaction and partial sequencing of 16S rDNA. Twenty-four antibiotics were used for the examination of antimicrobial resistance of Salmonella spp. isolates with the agar disk diffusion method (Kirby–Bauer technique). Multi-antibiotic resistance index and antibiotic resistance index (ARI)for Salmonella enterica isolates were calculated. Results: Twenty-one of 131 samples (16%) were positive for Salmonella spp. recovered from 9 (16%), 2 (11%), 4 (22.2%), and 6 (46%) samples of raw cow milk, fermented raw milk, and fresh locally made soft cheeses, Maasora and Ricotta), respectively. Samples of ice cream, milk powder, and infant formula showed no Salmonella spp. contamination. Only 9 of 21 (42.8%) isolates were confirmed as S. enterica by partial sequence 16S rDNA analysis. All isolates were resistant to amoxycillin, bacitracin, penicillin G, lincomycin, vancomycin, clindamycin,

Since being declared a pandemic in March 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the disease known as coronavirus disease (COVID-19), has brought difficult situations for citizens of nations worldwide. The effects, however, may be more severe for vulnerable communities, such as immigrants, who are already in desperate situations and under deteriorating conditions. There are still very limited data on how the pandemic is impacting migrant communities. Immigrant camps foster an environment that poses a great threat to the health of their inhabitants, especially at the time of a pandemic. Overcrowding, poor sanitation, inadequate health care, and difficulty containing contagious diseases are well documented in African immigration detention centers. Furthermore, they are unlikely to take priority in a moment in which governments are mobilizing all resources to care for their citizens. Their situation is even more complicated if they are hosted in corridors plagued by war, as in North Africa
