The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2, has challenged healthcare providers in maintaining the supply of critical personal protective equipment, including single-use respirators and surgical masks. Single-use respirators and surgical masks can reduce risks from the inhalation of airborne particles and microbial contamination. The recent high-volume demand for single-use respirators and surgical masks has resulted in many healthcare facilities considering processing to address critical shortages. The dry heat process of 80°C (176°F) for two hours (120 min) has been confirmed to be an appropriate method for single-use respirator and surgical mask processing.

The present study was carried out to knowing effect different storage periods of the microbial quality for the Powdered Infant Formula (PIF) after opening the tin, and ensuring from the safety note (after opening, use within 3 weeks). Thirty (30) samples of (PIF) from category (1 – 6 months) in five different types are collected from pharmacies and local markets in Baquba city / Iraq, which are used as substitutes for breast milk during the first day of opening the tin powders such as Total viable count, Total coliform count, Salmonella count and Yeast and Molds count. These experiments repeated at each week of same samples within (5) weeks. Results were obtained at opening the tin, Total viable count (less than 0.05 1.0 x 103 ±1.5x10 CFU/g) were significantly higher than Total Coliform count (less than 0.05 ± 0.3 x 10 CFU/g) and Total Salmonella count (less than 0.05 0 x 10 CFU/g) and Yeasts and Molds (less than 0.05 ± 0.3 x 10 CFU/g). while results obtained at fifth week were (less than 0.05 8.8 x 103 ±5.5x102 CFU/g), (less than 0.05 0.9 x 102 ± 0.4x101 CFU/g), (less than 0.05 0 x 10 CFU/g), (less than 0.05 9.5 x 10 ± 1.2x101 CFU /g) respectively. All samples of (PIF) having non-significant difference. These results compared to Iraqi Quality Standards (IQS), all the results from the opening samples to fifth week were within the range of IQS and USA Environmental Protection Agency (USEPA) and as indicates the hygienic condition of (PIF) without risk level for human health. also observed increase in microbial contamination in each week because increase the moisture content for powdered milk. Can be used more than 3 weeks after opening if stored in good conditions with good hygienic practices during milk preparation.

Background: The microorganisms can impend the life of health care professional and particularly the dental practitioners. They can be transmitted by different ways like airborne and droplet transmission. The current study was carried out to identify whether the arch wires that received from the manufactures are free from microbial contamination and to determine the bacterial species attached to the arch wires. Materials and Methods: This study involved eighty samples, consisted of two types of arch wires (nitinol and stainless-steel) from four companies (3M, G&H, Jiscop, OrthoTechnology). These wires inserted in a plane tube that contains 10 -ml of (Tris [tris(hydroxymethyl)aminomethane] and EDTA (ethylenediaminetetraacetic acid) tris-EDTA and brain heart infusion (BHI) broth. A 0.1 ml was withdrawn from the tube and spread on agar plates. The control groups consist of 16 plane tube (8 tubes with tris-EDTA and other 8 tubes with (BHI). Results: Microbial sampling yielded growth from 5 of the 80 arch wires. The predominant bacteria that isolated were Bacillus spp. No growth was recovered from 75 of the samples and from controls. The bacteria were isolated by BHI reagent and no growth was observed by tris-EDTA reagent with statistically significant difference (P<0.05). The Bacillus spp. found only in the G&H and Jiscop companies, however, no statistically significant difference was found among them (P>0.05). With regard to the presence and distribution of bacteria according to the types of wires, the present results clarified that cases of contamination with Bacillus spp. were found in the nitinol arch wires with statistically significant difference (P<0.05). Conclusions: The results of the current study revealed low count of bacterial contamination in the two types of companies (G&H and Jiscop). Not all materials that received from the manufactures are free from contamination and an effective sterilization regimen is needed to avoid cross-contamination.
